Sudoku is a great way for children to develop their logic skills whilst having fun at the same time. To solve a Sudoku puzzle, students needs to use a combination of logic and trial-and-error. Regular Sudoku is a 9 by 9 grid but these simpler puzzles are on a 4 by 4 grid, making the game easier to understand and beat, before moving onto the larger grids.

## How to play sudoku

The object of the game is to fill all empty squares so that the numbers 1 to 4 appear exactly once in each row, column and box. When teaching children how to solve sudoku puzzles, make sure they use a pencil so that they can rub out their mistakes.

First, get them to look for limited squares - squares for which there is only one possible answer. If they become stuck, get them to write all possibilities in each empty square. Having all the possible answers showing in each space can allow students to see the correct answer more easily. Remind them that puzzles get easier and easier to solve as more spaces are filled in. With a little bit of help and a push in the right direction your students will be flying through sudoku puzzles, in no time, all on their own.

Don't forget to model how to do one first. Put an example under the visualiser in your classroom to show the children how to solve it and also demonstrate your thought processes at the same time.
