Activities in this teaching pack include differentiated sets of cards to sequence the calculation steps that need to be used when subtracting a pair of four digit numbers for core and extension ability levels and three digit numbers for support ability levels with exchange between place value.

The interactive presentation gets the children to explore and record the calculation steps that need to be used when subtracting a pair of four digit numbers with exchange,

This lesson is part of a maths scheme of work to get the children to identify and illustrate the sequences of steps that can be used when completing standard written methods using decomposition to subtract pairs of numbers with four or more digits. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
