I first ran across Erich Friedman’s Plus Times Puzzles back in 2019. I have featured several of Erich’s puzzles on my blog before including Arrows Puzzle, Ducks and Snakes Puzzle, Equation Rotation Puzzle, Connect the Dots, and Hidden Equation. I was super excited when I discovered that he has an entire page of puzzles online called Erich’s Puzzle Palace.
This puzzle is just one of many free printable number challenges that I have created for my own classroom and am sharing with you!
Be sure to check out my entire collection of free printable math puzzles.
One of his puzzles that caught my eye was his Plus Times Puzzles. I bookmarked the page and jotted down a note on one of my million to do lists to create my own copy to use with my students.
In the Plus Times Puzzles, you are given a set of numbers as well as a plus sign, a times sign, and an equal sign. You must combine the digits and symbols given to form a correct mathematical equation. You may draw in parentheses, as needed.
Each Plus Times Puzzle has a unique solution.

Each puzzle is a separate deck of cards in a bag.
Each bag of laminated cards has a puzzle card which features the numbers involved in the puzzle as well as the letter of the puzzle.
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!
The rest of the cards in the bag are designed to be moved around while solving the puzzle.
I created tracking sheets for groups to keep track of which puzzles they have solved and which are still stumping them.
I think when I do this with groups next year, I will hole punch the letters as groups solve the puzzles.

I intentionally do not make answers to the printable puzzles and math activities 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.
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, as fun activities in their workplace, or as a birthday party escape room.
