# Product Square Puzzle

The Product Square Puzzle is a number placing logic puzzle which will test your multiplication knowledge.

## Instructions

Place the numbers 1 to 9 in the grid provided. The product of the numbers in each row and column is provided outside the table. One number (the number 2) has already been placed in the grid for you.

## Puzzle Source

This puzzle is from a collection of 199 different mathematical puzzles offered as a free download from IREM de Lyon. This is a top-notch puzzle resource if you speak French.

I sadly do not speak French, but I was able to use the Google Translate app to translate quite a few of the puzzle instructions in order to use them in my classroom. Other puzzles I typed up from this same resource is the U Sums Puzzle, Magic H Puzzle, Lines of 3 Puzzle, 4 x 4 Checkered Square Puzzle, Equal Sums Puzzle, Square Sums Puzzle, and the very popular Loops Puzzle.

This specific puzzle is #46 – Carré magique.

## Printing and Prepping the Puzzle

This puzzle is designed to print on letter-sized 8.5 x 11 inch paper, but you could easily scale it to print on A4 paper as well.

The number tile cards are designed to be printed on colored paper or cardstock. I like printing on Astrobrights paper to give my activities a pop of bright color.

You could also forego the number tile cards and slide the puzzle in a dry erase pocket and simply have the students write in the digits 3-9 by hand. The benefit of the tiles is that students can easily see what numbers they have and have not used yet.

MATH = LOVE RECOMMENDS…

I cannot imagine teaching math without my dry erase pockets! They instantly make any activity more engaging and save me countless hours at the copy machine since I can use the same class sets of copies year after year.

Here are my current go-to recommendations:

I used this puzzle in my classroom as one of my Puzzles of the Week. I prepared several copies of the puzzle and hung it on my dry erase board using a Charles Leonard magnetic pocket which I picked up from Amazon. They have been a real game-changer in my classroom organization!

## 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.
