Activities in this teaching pack include a set of cards to build a number line to twenty using words and digits so that their values can be compared and differentiated worksheets to select and record numbers that are one more and one less than different numbers to ten for support ability levels, to twenty for core ability levels and to thirty for extension ability levels.

The interactive presentation gets the children to explore and record the numbers that are one more and one less than different numbers to twenty.

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