Activities in this teaching pack include a differentiated set of templates to identify and record how to use standard calculations when adding and subtracting four and five digit numbers for core and extension ability levels and three and four digit numbers for support ability levels in a race against a partner.

The interactive presentation gets the children to explore how to use different standard calculations when adding and subtracting pairs of numbers.

This lesson is part of a maths scheme of work to get the children to use standard written methods of addition and subtraction to check calculated sums using inverse operations and solve problems with multi-step solutions. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
