Printable Heart Tangram Puzzle

This printable heart tangram puzzle is perfect for engaging students on Valentine’s Day or any day of the year! The goal of this puzzle is to arrange the ten pieces to form a heart.

When I saw a tweet from David Butler with a Valentine’s Day puzzle he created for his wife, I knew that I had to create a jumbo version of the puzzle for my classroom.

I placed disc magnets on the back of each laminated piece and placed the heart puzzle pieces as well as the instructions on my dry erase board.

A laminator is a MUST-HAVE for me as a math teacher! I spent my first six years as a teacher at a school with a broken laminator, so I had to find a way to laminate things myself.

I’ve had several laminators over the years. I currently use a Scotch laminator at home and a Swingline laminator at school.

I highly recommend splurging a bit on the actual laminator and buying the cheapest laminating pouches you can find!

My usual approach to using puzzles in the classroom is to post the puzzle and then wait and see what students do with it.

I’ve also shared a Cover the Heart Puzzle in the past that would also be perfect for Valentine’s Day or just the month of February in general.

David Butler shared the image file he created for this heart tangram puzzle on twitter. It became slightly fuzzy when I enlarged the pieces, so I combatted this by putting the disc magnets on the sides of the puzzle pieces featuring the outline.

I have included the original small version from David as well as the enlarged version in the download at the bottom of this post.

David says that this puzzle is slightly modified from a traditional heart tangram puzzle.

I put this Valentine’s Day heart puzzle up in my classroom earlier this week, and a student finally solved it today after several incorrect solution tries by other students! They were so proud of themselves!

I was hoping to get this heart puzzle up on my blog at the beginning of this week so that there would be plenty of time for teachers to prep it for their classrooms before Valentine’s Day. What I didn’t anticipate was that my entire blog would go down for multiple days.

My webhost ended up not being able to fix the issue, so I had to find a new webhost. I am learning that you definitely get what you pay for in terms of customer support when it comes to webhosting!

If you’ve had trouble accessing my site over the last week or so, I think all the issues should be fixed now. If you do get an error message, please send me a message!

Puzzle Solutions

I intentionally do not make answers to the printable math puzzles I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.

However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.

If you are a teacher who is using these puzzles in your classroom, please send me an email at with information about what you teach and where you teach. I will be happy to forward an answer key to you.
