Activities in this teaching pack include a set of differentiated worksheets to model how to use a formal written method to subtract pairs of two and three digit numbers with one exchange between place value to complete a step in the number calculations.

The interactive presentation gets the children to explore how to use concrete equipment and diagrams to subtract pairs of two and three digit numbers with one exchange between place value.

This lesson is part of a maths scheme of work to get the children to identify and practise using written calculation skills when subtracting pairs of numbers with up to three digits including exchange between place value. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
