In this Congruent Shapes Puzzle, students are given two colors of puzzle pieces. The task is to arrange the two colors of pieces to form two congruent shapes. You can rotate pieces and flip them over but not overlap them.
This Congruent Shapes Puzzle is the creation of the brilliant Erich Friedman and can be found in Puzzle Box, Volume 2, one of the books in my favorite series of puzzle books. It was this series of puzzle books that convinced me I should be using puzzles in my classroom.
In addition to publishing puzzles in books, Erich Friedman also has thousands of free puzzles on his website! If you love puzzles, I highly recommend taking a look around his Puzzle Palace!
I have featured several of Erich’s other puzzles before on the blog. Some of these include Arrows, Ducks and Snakes, 577 = 11111, and Plus Times Puzzles.
For this puzzle, you will need to print a set of instructions as well as the puzzle pieces on two separate colors of paper.
I printed the pieces on regular colored copy paper, laminated the pages, and then cut out the pieces.
I printed the puzzle pieces on regular colored paper before laminating them, but you could also print them on cardstock.
MATH = LOVE RECOMMENDS…
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!

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
Thank you for these. My students are so engaged and it’s been great listening to them think about them.
Thanks for sharing!
