What are Number Cross Puzzles?
A number cross puzzle is a rectangular grid (usually a square) each cell contains a number. Additionally, numbers are placed in the row above the grid and in the column to the left of the grid.
In a number cross puzzle, your task is to cross out cells of the grid until the sum of each row and column equals the values written above and beside the grid.
Each puzzle has a single unique solution.
Example Puzzle and Solution
Here’s a sample number cross puzzle and solution to help you understand the goal of this logic puzzle.
Puzzles Sizes and Difficulty Levels
I hope to continue to add free printable files for different sizes of number cross puzzles.
As the puzzle grid size grows, the level of difficulty of the puzzle increases. The easiest number cross puzzles are the 5×5 puzzles.
Additionally, each different size of puzzle is available in three different levels of difficulty: easy, medium, and hard.
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!
