# Subtraction Puzzle

### Purpose:

The purpose of this activity is to help your child to recall the subtraction basic facts up to 20.

### Link to the Number Framework:

Number Facts, Stage 6

### What you need:

Puzzle Board (PDF, 40 KB). You can print this or make your own.

### What to do:

Cut out the puzzle and give the pieces to your child.
Ask your child to arrange the pieces back into the 3 by 3 grid so that sides of the touching pieces match. For example, 11 - 4 needs to match 7.
Two hints you may wish to give your child:
1. When the puzzle is complete none of the pieces will be orientated so the numbers are upside down.
2. The piece with 2 blank sides can go in the top left corner of the puzzle.

### What to expect your child to do:

To use their subtraction basic facts to solve the puzzle.

### Variation:

Make your own puzzle. Puzzles where every fact has a different answer are easier to solve.
