6x6 Sudoku

Puzzles for growing problem-solvers

This set includes 6x6 sudoku grids with different starting clues and levels of challenge. Younger children can begin with puzzles that have many numbers already filled in, while older children can try grids that need more careful checking. Each puzzle uses the numbers 1 to 6, with no repeated number in a row, column or small box. Children do not need advanced maths to solve them. They need to notice patterns, keep track of choices and change a guess when it does not fit. The pages suit home practice, early primary classrooms and quiet independent work.

Simple ways to use the pages

Give your child one puzzle after school, during a quiet weekend activity or as a short warm-up before maths. In class, place a puzzle in a work station, use it for early finishers or solve the first few squares together on the board. Ask children to explain why a number can or cannot go in a space, rather than asking them to work quickly. Pair children at different levels so one child reads the row and the other checks the columns. For a wider logic activity, try Sudoku for Kids or 4x4 Sudoku next.

Helping with common Sudoku mistakes

Children often look only across a row and forget to check the column and box. Encourage a three-part check before writing a number: scan the row, scan the column, then scan the small box. Another common mistake is placing a number because it seems possible, without checking the other empty spaces. Ask your child to circle two or three possible numbers lightly, then remove choices as new clues appear. If a puzzle starts to feel confusing, return to the last number that was certain and check from there. A pencil and eraser make this process less frustrating.
