Puzzle Workbooks for Kids - Updated Each Month!

Sudoku is hugely popular for a reason, and kids are not immune to its lure. On this page, you will find everything you need to customize all of your Sudoku puzzles for your classroom. You can create puzzles using either shapes or numbers, and your grids can be 4x4, 6x6, or 9x9. You can use edHelper's premade options if you are short on time (with no hints, some hints, or more hints), or you can do all of the customizing yourself. Your students won't even realize they are doing schoolwork, much less improving their critical thinking skills when they are working these Sudoku puzzles!

How do you solve a Sudoku?
Fill in the grid so that every row, every column, and every 3x3 box contains the numbers 1 through to 9. There is only one solution to the puzzle.
