Activities in this teaching pack include differentiated worksheets to select and record matching sets of three numbers that make different addition sums to twenty for core and extension ability levels and to ten for support ability levels when working with cubes and pictures.

The interactive presentation gets the children to explore how to record sets of numbers that make sums to ten and twenty using cubes and pictures to model calculations.

This lesson is part of a maths scheme of work to get the children to practise using different mental and informal written calculations to add pairs of one and two digit numbers using concrete objects and diagrams to support calculations. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
