Activities in this teaching pack include differentiated sets of cards to select and record different pairs of numbers that sum to totals to twenty for core and extension ability levels and to ten for support ability levels using concrete equipment to record the number bonds.

The interactive presentation gets the children to explore and record how to match different pairs of numbers that sum to totals within twenty.

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.
