Activities in this teaching pack include differentiated worksheets and cards to play games to identify and record pairs of numbers that make sums to twenty for core and extension ability levels and to ten for support ability levels when using addition calculation skills.

The interactive presentation gets the children to explore and record different pairs of numbers that make sums to twenty when playing some number games.

This lesson is part of a maths scheme of work to get the children to investigate and model how to use mental calculation techniques when working with concrete objects and diagrams to identify pairs of numbers that make sums to twenty. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
