Activities in this teaching pack include differentiated templates to practise adding different two digit numbers and tens for support ability levels and three digit numbers and tens for core and extension ability levels using diagrams to model exchange to place value during each calculation.

The interactive presentation gets the children to explore how to count in steps of ten to add a three digit number and tens with exchange between place value.

This lesson is part of a maths scheme of work to get the children to practise and refine different techniques for addition using facts about numbers to support mental calculations including adding multiples of hundreds and tens and utilising number bonds. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
