Activities in this teaching pack include a set of differentiated worksheets to identify and record how to subtract pairs of two and three digit numbers using a formal written method with exchange between place value for core and extension ability levels and no exchange for support ability levels.

The interactive presentation gets the children to explore how to model how to use a formal written method to subtract pairs of two and three digit numbers with exchange between place.

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.
