How to make a large sudoku bulletin board

These are ideas for how to make a large Sudoku board. A large Sudoku bulletin board in your classroom makes a good activity for early finishers. You would need to have two differnt sets of numbers and should have them in different colors, one color to set up the original puzzle, and the other color in ziplock backs or a pocket chart for the students to use for solving the puzzle. Each number card should be laminated and Velcro dots can be stuck on the backs. The students would be told that they cannot move the original numbers.

Another method would be to laminate your Sudoku board, then write with a sharpie over the laminate. Once solved, clean off the sharpie by writing over the numbers with a whiteboard marker and wipe off. Then write the new numbers with sharpie. And have students add Velcro number cards to solve. This way, you can set the numbers on the grid and the students can add in the rest to solve. It should be noted that if you laminate the puzzle with numbers, it can only be solved so many times before students start to memorize it and you have to make a whole new one.

Teachers should limit the number of students who can use the Sudoku bulletin board (at the same time), and if they are using it as early finishers, they would have to whisper while using it because others are still working.

  • Make a push pin Sudoku game on the wall: Use a 3×3 grid felt board tile on the wall and use felt numbers with push pins as the starter numbers. Students can use the laminated number cards with Velcro dots on the back as the numbers to solve it.
  • Use sudoku whiteboards: These Sudoku whiteboards allow you to copy out the puzzle with dry-erase markers, and use multiple colors while solving it.
