Activities in this teaching pack include a set of differentiated worksheets to model how to complete calculations when adding pairs of four digit numbers for core and extension ability levels and three digit numbers for support ability levels with one exchange between place value.

The interactive presentation gets the children to explore how to add pairs of three and four digit numbers with one exchange between place value.

This lesson is part of a maths scheme of work to get the children to investigate different ways of adding three and four digit numbers using mental and formal written calculations with 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.
