This math valentine square puzzle combines cheesy mathematical valentines with a square edge-matching puzzle. Can you correctly assemble the pieces to create a 3×3 square?

This math-themed Valentine’s Day puzzle was inspired by the classic 9-piece scramble squares puzzles which can be purchased with different themes. The goal of these puzzles is to assemble the pieces in a 3×3 square by correctly matching the edges of each puzzle piece.

This type of puzzle is considered an edge-matching puzzle.

I had a lot of fun learning how to make this puzzle. I first started creating it in Microsoft Publisher which is my go-to program for creating files for my classroom. But I ended up making it in LaTeX. This project required a bit more coding skills than my only previous LaTeX projects – my mystery coordinate plane tangram puzzles.

## Instructions

After printing the math valentine square puzzle, cut apart the 9 pieces. Assemble them into a 3×3 grid so that the puzzle pieces match along each edge.

## Ideas for Modifying the Puzzle

Looking to make the puzzle a bit easier? My best advice for modifying this puzzle would be to tell students which piece is in the top corner of the solved puzzle.

## Math Valentine Conversation Hearts

When the puzzle is solved correctly, these four different math-themed conversation hearts will be formed throughout the puzzle.

I decided that these conversation hearts would make cute posters to hang up around a math classroom on Valentine’s Day, so I enlarged them to create free printable math valentine posters.

## 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 sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.
