Activities in this teaching pack include a set of differentiated worksheets to select and record number sums that are one more than numbers to ten for support ability levels, to twenty for core ability levels and to thirty for extension ability levels when using counting on to support each addition calculation.

The interactive presentation gets the children to explore the matching number sums that are one more than numbers to ten, twenty and thirty when using number spinners.

This lesson is part of a maths scheme of work to get the children to identify and record the matching addition sums that are one more than numbers to twenty supported by concrete objects, pictorial diagrams and informal calculation methods. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
