Use these Sudoku Squares to make a giant Sudoku game board on a wall in your classroom! I laminate them and have students solve a different puzzle each week. Students can work on the puzzle if they finish early. Also, you can have drawings from the participants each week to encourage students to try it out!
The squares are 12x12. You can take them to your local office supply store and have them print them out for you. If you ask them to use the 'blueprint' paper and price, they will usually go for that! :)
