Subtraction for kids aged 9-10

Children 9-10 years are subtracting using two, three and four digit numbers. They can use a range of strategies and talk about their working out. Increasingly kids are working with word problems so fun activities where you model this process to your child are important.

Choose a three-digit number without repeating any digit and without using zero, for example 381. You reverse the order of the digits to create a second number, in this case 183. The child subtracts the smaller number from the larger and records this as a number sentence. The answer is used to start another reversal subtraction. Play continues until zero is reached. The process could be repeated for other three-digit numbers. Together with your child discuss any patterns they observe.
