These free area & perimeter task cards are designed to provide geometry problem solving practice for your students..
Use these area & perimeter task cards to provide your students with problem solving practice during your geometry focus.
This is a set of 20 word problem task cards at varying levels that address the standards for calculating area and perimeter.
As always, this set has been created to be a free resource for classrooms and homes. Please copy and use for your personal use. They may not be sold or modified and sold in any way.
These cards might be used at a math center where students focus on problem solving. They might also be used in small groups where each group is given a different problem to solve.
These cards are designed to provide practice for students who have been taught the skills of finding area and perimeter. They are not designed to teach. It is important to make sure students have an understanding of the skills before asking them to complete any of the task cards.
The first eight word problems are fairly straight forward types of story problems calling for students to think about real-world type situations in which they may need to calculate area or perimeter.
Task cards #9 – #16 require students to draw shapes meeting certain area or perimeter stipulations. These are more open-ended tasks because the shapes students draw can all look very different.
The final four tasks are more challenging problems that will require students to use various problem solving strategies that include drawing pictures, using logical reasoning and guess and check. These would best be used with your most skilled mathematicians or for group work.

In his book “How to Solve It,” George Pólya (1945) said, “One of the most important tasks of the teacher is to help his students. This task is not quite easy; it demands time, practice, devotion, and sound principles. The student should acquire as much experience of independent work as possible. But if he is left alone with his problem without any help, he may make no progress at all. If the teacher helps too much, nothing is left to the student. The teacher should help, but not too much and not too little, so that the student shall have a reasonable share of the work.” (page 1)
What is a problem in mathematics? A problem is “any task or activity for which the students have no prescribed or memorized rules or methods, nor is there a perception by students that there is a specific ‘correct’ solution method” (Hiebert, et. al., 1997). Problem solving in mathematics is one of the most important topics to teach; learning to problem solve helps students develop a sense of solving real-life problems and apply mathematics to real world situations. It is also used for a deeper understanding of mathematical concepts. Learning “math facts” is not enough; students must also learn how to use these facts to develop their thinking skills.
According to NCTM (2010), the term “problem solving” refers to mathematical tasks that have the potential to provide intellectual challenges for enhancing students’ mathematical understanding and development. When you first hear “problem solving,” what do you think about? Story problems or word problems? Story problems may be limited to and not “problematic” enough. For example, you may ask students to find the area of a rectangle, given the length and width. This type of problem is an exercise in computation and can be completed mindlessly without understanding the concept of area. Worthwhile problems includes problems that are truly problematic and have the potential to provide contexts for students’ mathematical development.
There are three ways to solve problems: teaching for problem solving, teaching about problem solving, and teaching through problem solving.
Teaching for problem solving begins with learning a skill. For example, students are learning how to multiply a two-digit number by a one-digit number, and the story problems you select are multiplication problems. Be sure when you are teaching for problem solving, you select or develop tasks that can promote the development of mathematical understanding.
Teaching about problem solving begins with suggested strategies to solve a problem. For example, “draw a picture,” “make a table,” etc. You may see posters in teachers’ classrooms of the “Problem Solving Method” such as: 1) Read the problem, 2) Devise a plan, 3) Solve the problem, and 4) Check your work. There is little or no evidence that students’ problem-solving abilities are improved when teaching about problem solving. Students will see a word problem as a separate endeavor and focus on the steps to follow rather than the mathematics. In addition, students will tend to use trial and error instead of focusing on sense making.
Teaching through problem solving focuses students’ attention on ideas and sense making and develops mathematical practices. Teaching through problem solving also develops a student’s confidence and builds on their strengths. It allows for collaboration among students and engages students in their own learning.
Consider the following worthwhile-problem criteria developed by Lappan and Phillips (1998):
Of course, not every problem will include all of the above. Sometimes, you will choose a problem because your students need an opportunity to practice a certain skill.
Key features of a good mathematics problem includes:
Problem solving is not a neat and orderly process. Think about needlework. On the front side, it is neat and perfect and pretty.
But look at the b ack.
It is messy and full of knots and loops. Problem solving in mathematics is also like this and we need to help our students be “messy” with problem solving; they need to go through those knots and loops and learn how to solve problems with the teacher’s guidance.
When you teach through problem solving , your students are focused on ideas and sense-making and they develop confidence in mathematics!
Selecting activities and/or tasks is the most significant decision teachers make that will affect students’ learning. Consider the following questions:
By definition, a “ low floor/high ceiling task ” is a mathematical activity where everyone in the group can begin and then work on at their own level of engagement. Low Floor High Ceiling Tasks are activities that everyone can begin and work on based on their own level, and have many possibilities for students to do more challenging mathematics. One gauge of knowing whether an activity is a Low Floor High Ceiling Task is when the work on the problems becomes more important than the answer itself, and leads to rich mathematical discourse [Hover: ways of representing, thinking, talking, agreeing, and disagreeing; the way ideas are exchanged and what the ideas entail; and as being shaped by the tasks in which students engage as well as by the nature of the learning environment].
The strengths of using Low Floor High Ceiling Tasks:
Examples of some Low Floor High Ceiling Tasks can be found at the following sites:
Math in 3-Acts was developed by Dan Meyer to spark an interest in and engage students in thought-provoking mathematical inquiry. Math in 3-Acts is a whole-group mathematics task consisting of three distinct parts:
Act One is about noticing and wondering. The teacher shares with students an image, video, or other situation that is engaging and perplexing. Students then generate questions about the situation.
In Act Two , the teacher offers some information for the students to use as they find the solutions to the problem.
Act Three is the “reveal.” Students share their thinking as well as their solutions.
“Math in 3 Acts” is a fun way to engage your students, there is a low entry point that gives students confidence, there are multiple paths to a solution, and it encourages students to work in groups to solve the problem. Some examples of Math in 3-Acts can be found at the following websites:
Number talks are brief, 5-15 minute discussions that focus on student solutions for a mental math computation problem. Students share their different mental math processes aloud while the teacher records their thinking visually on a chart or board. In addition, students learn from each other’s strategies as they question, critique, or build on the strategies that are shared.. To use a “number talk,” you would include the following steps:
“Number Talks” can be used as an introduction, a warm up to a lesson, or an extension. Some examples of Number Talks can be found at the following websites:
“This is easy.” Three little words that can have a big impact on students. What may be “easy” for one person, may be more “difficult” for someone else. And saying “this is easy” defeats the purpose of a growth mindset classroom, where students are comfortable making mistakes.
When the teacher says, “this is easy,” students may think,
Instead, you and your students could say the following:
Tracy Zager wrote a short article, “This is easy”: The Little Phrase That Causes Big Problems” that can give you more information. Read Tracy Zager’s article here.
Do you want your students to memorize concepts, or do you want them to understand and apply the mathematics for different situations?
What is a “worksheet” in mathematics? It is a paper and pencil assignment when no other materials are used. A worksheet does not allow your students to use hands-on materials/manipulatives [Hover: physical objects that are used as teaching tools to engage students in the hands-on learning of mathematics]; and worksheets are many times “naked number” with no context. And a worksheet should not be used to enhance a hands-on activity.
Students need time to explore and manipulate materials in order to learn the mathematics concept. Worksheets are just a test of rote memory. Students need to develop those higher-order thinking skills, and worksheets will not allow them to do that.
One productive belief from the NCTM publication, Principles to Action (2014), states, “Students at all grade levels can benefit from the use of physical and virtual manipulative materials to provide visual models of a range of mathematical ideas.”
You may need an “activity sheet,” a “graphic organizer,” etc. as you plan your mathematics activities/lessons, but be sure to include hands-on manipulatives. Using manipulatives can

In our culture, we are bombarded with messages implying that some people are good at math and some people aren’t. There’s this notion that some people have that elusive “math gene” and some people don’t. Overcoming these negative attitudes and baggage to encourage kids that they can in fact learn and enjoy math and there is actually no such thing as a “math person,” is a challenge. But more and more research is showing up that kids with a growth mindset towards math do better on standardized tests, are more engaged in class and have a better attitude about math in general. Today I want to focus on how rich math tasks can excite and engage kids and begin to develop a growth mindset . As you go through this list of math tasks that promote a growth mindset , pick out your favorites to try with your kids!
* Please Note : This post contains affiliate links which help support the work of this site. Read our full disclosure here .*
The notion of a fixed mindset versus a growth mindset began with the work of Carol Dweck . She explains that everyone has a mindset or idea about how they learn. Those with a fixed mindset believe that you can’t change your level of intelligence. You can only learn so much or go so far.
Those with a growth mindset, on the other hand, view intelligence as something that can be achieved through hard work and perseverance .
In other words, “smarts” is not something you’re born with, it’s something that can develop over time if you’re willing to put in the effort.
Because so many in our culture have a fixed mindset towards math, it is important that we do what we can to dispel these notions as more and more brain research sheds light on how we learn new things. Because the truth is that our brains grow when we make mistakes . And our brains can grow and change and adapt even if half of the brain is removed .
If the human brain is capable of these remarkable achievements, surely our brains are capable of learning Algebra !
Changing our own mindset towards learning math can be a challenge, much less changing our kids’ mindsets . But it’s not impossible.
One thing that has to change is the way math is viewed . All too often, math is seen as a closed, fixed subject to be memorized and then forgotten.
But math is a creative, open and exciting topic that touches every single aspect of our lives! We see and use math everyday, and to help kids see that they can learn and achieve math at high levels, we have to get them excited about it.
One way to encourage kids to see math as creative and present in the world around us is to explore math in nature . These concepts are great because they are accessible for young kids but complex enough to challenge older, advanced learners .
Jo Boaler, in her book Mathematical Mindsets , explains the importance of rich and open math tasks. No matter what curriculum you use, you are the teacher and have the opportunity to present math in a way that is engaging.
In the book, Boaler discusses several ways tasks can be rich and engaging for kids . Here is a quick overview:
Using these criteria, I want to share a growing list of math tasks and websites where you can find meaningful lessons to engage your kids in math learning and teach with a growth mindset .
And if you have any ideas to add to this list, be sure to share in the comments!

Providing students with opportunities to grapple with math has led to amazing things happening in my class. Students are totally excited and are driven to figure out not just how to solve a problem but why it works.
Watch two rivers’s teachers and students at work on problem-based tasks in math.
Problem-based tasks are math lessons built around a single, compelling problem. The problems are truly “problematic” for students — that is, they do not offer an immediate solution.
The problems provide an opportunity for students to build conceptual understanding. Problem-based tasks require students to apply their current understanding and skills to new contexts that highlight core math concepts. For example, when students solve a problem that could be solved with multiplication before they have formally been taught what multiplication is and how it works, they build an understanding that multiplication is repeated addition.
Well-designed problem-based tasks provide multiple entry points for students to engage in problem solving, ensuring that all students have access to the same concepts. When students solve the problems in different ways—including drawing pictures, acting out the problem, writing algorithms, and using manipulatives—they make connections between the variety of models that all accurately illustrate the underlying mathematics.

There must be many great sources of lessons that I am missing. Please leave me a comment to let me know which websites I need to add to the search engine.
Wow! This is amazing! Thank you so much for doing this. One other great site I’ve found is HungryTeacher.com It has some very cool project ideas, similar to Mathalicious but not as detailed. Keep up the great work!
@EdCamposJR
Thank you Ed. I actually added HungryTeacher.com to the search engine but forgot to add it to the list of sites on this page so thanks for the heads up.
This is going be amazing for me.
This is so cool and helpful. Thank you so much for this. http://www.gogeometry.com has some challenging geometry problems.
Hi Teresa. Glad it is useful. I searched around gogeometry.com but couldn’t find anything like a problem-based lesson. Could you give me a specific link to a lesson to check out?
Thank you for this search engine. It is very helpful.
What about adding this site? http://ell.stanford.edu/teaching_resources/math
There are only a few tasks here but they focus in on our ELs.
Hi Jennifer. There are some cool lessons there but I don’t know if they would fall under the category of problem based lessons I am aspiring to capture here. Thanks for your idea!
nice work, could you share how you set this up? I like the idea of embedding a search to only look through certain sites.
Also I suggest Dan Meyer’s Graphing Stories, Fawn Nguyen’s blog and the math lab: http://www.themathlab.com/Algebra/linear%20functions%20regressions%20slope/regression%20lessons/barbie%20bungee/barbbungee.htm
Hi Shaun. Check out Google’s Custom Search at https://www.google.com/cse/ . That is where you can create your own search engine. It is rather robust but not perfect. For example, it is very challenging to include a site but exclude the blog posts.
Regarding your suggestions, those are all great sites but Graphing Stories and Fawn’s awesome blog are not really within the problem-based learning domain so that is why I haven’t included them. That being said, both of them have been links on the right side of my blog for quite some time so I definitely value them both.
I am having trouble getting the Barbie Bungee jump to load but I will try again another time to check it out.
This is an old post, but I am trying to develop my own 3Acts and have a resource page of them as well.
Hi Bryan. All of your lessons are included since they are posted on 101qs.com. Thanks!
Amazing resource!!! Thank You for creating this search engine!!! 🙂
Have you checked out the website: http://davidwees.com/
He has some pretty useful articles, especially on strategies for formative assessment.
Full disclosure: He’s a colleague of mine so I am biased, but I do get a lot out of what he shares and apply to my own work.
Thanks Blue. David is great but I don’t believe he is creating any problem-based lessons. If he is, please list a link to where I can find them.
http://reasonandwonder.com
Thanks Kevin. Can’t believe I forgot Michael. Problem fixed.
Rob, have you come across Tuva yet? Focused on data-based problems for math, science, and many other subjects. You can check it out at tuvalabs.com.
Hi, thanks for the resource!
Would you consider these to be examples of problem-based learning?
https://aofradkin.wordpress.com/2015/03/18/facing-the-impossible/ https://aofradkin.wordpress.com/2014/11/11/stick-figures/ https://aofradkin.wordpress.com/2014/10/10/fun-with-tetraminos/
Hello. To me the answer is both yes and no. Clearly these are problems that you can base a lesson around. However they are not of the style that we are including in this search engine. If you are interested in examples of elementary tasks of this style, check out Graham Fletcher’s problems here: http://gfletchy.com/3-act-lessons/ .
I was so excited to find this resource that I immediately emailed all of the teachers in my department a link to this post. Then, I realized that I had a double block of Algebra I approaching in 15 minutes and I could use this search tool to find a resource that might raise the engagement level for my students. Sure enough…I typed “graphing quadratic equations” into the search box, and numerous resources appeared. I selected the second hit on “Angry Birds”,and it fit seamlessly into my lesson plan. The students asked such great questions and were able to clearly answer questions about the vertex, x-intercepts, and orientation of the quadratic equations that modeled the paths of the angry bird. Of course, then I had to send out another email to my department ranting and raving about my math rush.
Isn’t it cool when it works out! Glad to hear it was useful for you in a tight situation.
What about http://www.openmiddle.com ? Thanks so much for this! You are a life saver.
Hi Alex. Obviously I love Open Middle, but it doesn’t seem to be a good fit here. This search engine is more for math modeling problems also known as 3-Act Tasks or problem-based lessons. What do you think?
Will. Change. My. Life. So excited to share this!!!!
Hi Robert, I will be sharing this with my colleagues at school that focus on the Math contents… Thanks for a great resource on behalf of all those teacher who need a little more help in the topics area.
That’s great Sonia. I hope they find it useful.
Thanks for this very useful resource.
Great search engine. Didn’t know that you could have a custom search engine.
Have you looked at nzmaths?
https://nzmaths.co.nz/problem-solving
Hi Ben. I haven’t heard of this but it seems like there are some useful problems there. I’ll add it to the list. Much appreciated!
I LOVE THIS! I’m so excited to have a search engine that will only search for mathematical tasks! I’m sharing it with everyone I know:). Thank you so much, Robert!!
Glad you like it Karen. Definitely a time saver.
Hi Robert. I love that you did this. It makes it easier to get teachers to try these out. I also have another site – tapintoteenminds.com. He has developed some tasks using the 3-Act format.
Hi Nadirah. I actually have that site on the list under Kyle Pearce, who created that site and those lessons.
Of course you did Robert! Silly me.
Thanks! This is amazing and such a great idea! Is there a way to embed this link into our own sites?
Can you explain more about what you mean to “embed this link”? You can put a link to this blog post on your own site, that’s no problem.
Hey! I think this is a great list of resources and so thankful for the list. It has saved me in the last a lot. I am in my grad school class and researching on PBL. I am a little confused how this qualifies has PBL and not just projects or really good math lessons. My research suggests that with PBL the learning is happening through the project and the project is not a activity we tack on at the end. I also read, “While the learning context is common to all groups, the paths may differ considerably—all leading to distinct learning. In project-based learning all students engage in a common project with unclear processes but clearly identified expected outcomes.” Can you speak a little bit about your thoughts on PBL. I am trying to find some math teachers I look up to and follow to help me learn about PBL in a secondary classroom. Please respond or email me at [email protected]
Hi Virginia. Thanks for this question. I should be clear that this is a PROBLEM-based search engine and not a PROJECT-based search engine. While the two have similarities, it sounds like you are talking about project based lessons and not what I am focusing on.
I don’t do a lot with project based learning so unfortunately I’m not a good resource for you there. Sorry! If you want to learn more about problem based learning, you can read more here: http://robertkaplinsky.com/tag/problem-based-learning-2/ .
Youcubed certainly has many options as well!
Thanks Merryl. I’m not aware of any problems that Youcubed has that would be considered problem-based lessons like 3-act tasks and the ones on my site. If you can point me in the right direction, I’d love to check them out.
This is awesome! Is there any way to take out Mathalicious since it is now requires a subscription?
Hi Danielle. I understand where you’re coming from, but that isn’t a problem for me. You often get what you pay for, and as much as it feels nice to get lessons for free, the Mathalicious team’s full time job is creating high quality lessons for educators. They deserve to be compensated.
Personally, I prefer to be aware of what’s out there so that I can choose what’s best from me. Sometimes it will be worth paying for.
Have you looked at illustrative mathematics or exemplars? Both have good problem based questions.
Thanks Sarah. I think this issue is stems from the word “problem” being so broad. Yes, I have looked at those problems, but they aren’t like the 3-act tasks and other problem-based lessons I am looking for with this search engine. I want problems that are more like these: https://robertkaplinsky.com/lessons/
Is it possible to add the Phillips Exeter sets? Could it search through their PDF files?
I’m not sure Dave. Do you have a link to an example?
What about Ilustrative Mathematics? https://www.illustrativemathematics.org/
Hi Brian. I think this issue is stems from the word “problem” being so broad. Yes, I have looked at those problems, but they aren’t like the 3-act tasks and other problem-based lessons I am looking for with this search engine. I want problems that are more like these: https://robertkaplinsky.com/lessons/
So many comments – did anyone else suggested the Illustrative Mathematics site
Hi Angela. Yes, a few others have suggested it. It’s not a good fit for the kinds of problems I’m referring to (which are more like you’d find on my lessons page or 3-act tasks). Thanks!
Hi. Thanks for creating that.
I’m not sure if either of these qualify, but one you may want to consider is https://mathsolutions.com/free-resources/ because it has stuff from Marilyn Burns.
I also love Steve Wyborney’s site: https://stevewyborney.com/2018/11/esti-mysteries-estimation-meets-math-mysteries/
My students really enjoy the esti-mysteries.
Thanks Jeff. Those are all great resources. The kinds of problems we’re trying to include here are more real-world or three-act task style problems, so this is not a great fit for this particular search engine.
This is AWESOME! Thank you. Wide Open School ( https://wideopenschool.org/#grades-6-8/ ) is a great resource also.
Thanks Jenny. There’s lots of great stuff there. Unfortunately, the kinds of problems we’re trying to include here are more real-world or three-act task style problems, so this is not a great fit for this particular search engine.
What a wonderful one-stop shop for problem solving tasks. I would love to link them all to my site called CURIOSEDY. I wonder if you think Curiosedy could be added to the list as it has open-ended rich tasks as well as multi-step problem solving. Would love your thoughts. Thanks again for this.
Thanks for sharing this, Francois. I can see lots of potential in what you’re doing. The kinds of tasks in this search engine (more like 3-act tasks) are a bit different from your approach, but both have value. So it’s not a great fit for this search engine but keep it going as it’ll help other students.
Hi Robert, Mark Chubb has some great stuff, especially around spatial reasoning. He deserves a spot! Thanks.
Mark definitely has some great resources. Unfortunately they’re not the kinds of problems for this search engine. I’m thinking more like problems with real world context.
I believe the hyperlink for Beth Brandenburg is not working.
Thanks for catching that. I guess her site is no longer active. I just went through all of them and updated it accordingly.
Hi Robert, Thanks for sharing. Check out https://www.resolve.edu.au/teaching-resources There are many lessons on this that have problem solving and inquiry tasks. My favourites are the circumference and area of circles. Hope this fits the style of tasks you are looking for.
Thanks Lorna. This is a bit different style of problem than what I’m going for. Ideally, I’m looking for problems that are more contextual without necessarily being a word problem. These are definitely great problems, but a different kind than I’m using with this search engine. Thanks again.

I have a rule about the first day of school: always do some math. No, that doesn't mean you have to start Lesson 1.1 as soon as students walk through the door, but it does mean that you should give your students a preview of the kind of thinking, reasoning, puzzling, and sense-making that they'll be doing in your class this year. Ideally, students will be so highly engaged that they barely even recognize they're doing math -- and certainly not the kind of math they're used to in school.
I also have an inordinate appreciation for what I call "interesting problems". These are tasks that use mathematical thinking and strategy, but don't require specific content knowledge like the formula for the equation of a circle or knowing what a composite function does. They are highly accessible, highly engaging, and have multiple solution strategies. The task itself can be explained in a few sentences and students can work on them for 20 minutes or 2 hours, depending on how far they want to take it. I scour the internet for tasks like these and have been collecting them for YEARS on my computer. I decided this was the year to bring them to the light and share them with the Math Medic community.
These tasks don't require formal content knowledge, but they do help students engage in the mathematical practices and develop mathematical habits of mind, such as:
Looking for and making use of structure
Representing one's thinking
Working systematically
Visualizing
Developing a convincing argument
Conjecturing and generalizing
While I've curated this list with high school students in mind, many of these tasks could be done with middle schoolers or even with adults. The inspiration for these questions came from all over this great big internet, but have been adapted and reformatted for classroom use. So, without further ado, here are my (current) top 10 "interesting problems" to do on the first day of school.
A linear context in a LOT of disguise. Many solution strategies and great opportunities for representing one's thinking with a model or visual.
This one is set up with multiple parts providing lots of natural extensions. Thinking about a number's properties is key to this task! Make sure to print the 100s chart that is on page two on a separate sheet of paper. You can offer it to everyone or as an optional support.
Loads of solution strategies on this one as well. Your teacher brain might scream system of equations with 4 variables, but you'll be surprised at the intuitive solutions your students find to solve this problem.
Perfect after a summer of olympics. Students deal with rates in this problem, which is an important concept for any age group and relevant for any math course.
This one's been famous for a long time but I'm sharing it anyway because students do great with it!
This one and the next two all encourage students to think systematically. There's a brute force solution but making use of structure will illuminate an easier way.
This is a good intro to thinking systematically and has a nice extension. I would use this in an Algebra 1 or Geometry course.
This one is very difficult, so we recommend saving it for your Precalc or above courses.
This one is the most recent in my collection and I'm still thinking about the extension part!
I've often done this one with Geometry students because of the shapes and visual reasoning components.
Editable versions of these tasks can be found in this Google Drive folder .
Pick ONE task for students to work on. We don't recommend giving multiple tasks back-to-back because it can start to feel like a worksheet, rather than a puzzle.
Solve the problem yourself first! We are purposefully not giving solutions here , so make sure you've wrestled with the problem yourself before handing it out to students.
Have students work on these in groups of 2, 3, or 4. Make sure they have enough materials available to hash out their ideas and represent their strategies. These are great to do on vertical non-permanent surfaces or poster paper.
Decide how long you will let students work. If doing this on the first day of school, we recommend about 20 minutes. If students don't have a solution by then, that is totally fine. A surprising number of them will keep thinking about the problem throughout the day or even at home.
Be ready with some extensions for groups who finish early, but make sure they understand what "done" means. Have they clearly communicated their strategy? Have they convinced themselves and others that their strategy will hold up? If giving an extension, make sure it's related to the given task, not just a different task. It's important that students are challenged in the depth of their reasoning, not in the quantity of problems.
If you're looking for more tasks like these, I highly recommend the NRICH site from the University of Cambridge.
