Activities in this teaching pack include templates to use diagrams to model how to add pairs of numbers by partitioning them into their matching sets of tens and ones for core and extension ability levels and sums to ten for support ability levels.

The interactive presentation gets the children to explore how to add pairs of two and one digit numbers by partitioning them into tens and ones.

This lesson is part of a maths scheme of work to get the children to model and illustrate how to add pairs of two digit numbers with multiples of tens and ones and other two digit numbers using concrete equipment, diagrams and informal written calculations. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
