Activities in this teaching pack include differentiated worksheets to select different numbers to thirty for support ability levels, to fifty for core ability levels and to one hundred for extension ability levels to change by adding a matching number of ones when using counting on.

The interactive presentation gets the children to explore how to use counting on to add pairs of two digit numbers and ones to identify sums of matching sets of money coins.

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.
