Now that children are more familiar with how to exchange from one place value column when using column subtraction, why not extend their understanding with a discussion problem?

This Year 4 Subtract Two 4-Digit Numbers (1 Exchange) Discussion Problem is designed to give children the chance to discuss and share their understanding on exchanging from one place value column in two questions using real-life scenarios.

Designed to offer pupils the chance to work collaboratively using their investigative skills, this worksheet is a excellent way of consolidating learning on subtraction. The answers are provided for ease of marking, either by a class adult or so that children can self-mark.
