Activities in this teaching pack include a worksheet to select and record different multiples of ten that can be used when performing number calculations to subtract pairs of four digit numbers and tens by utilising the technique of counting back to find each sum.

The interactive presentation gets the children to explore changes to the place value of the digits in a number when subtracting a four digit number and tens.

This lesson is part of a maths scheme of work to get the children to practise mental and written calculation strategies to subtract pairs of numbers with up to four digits including exchange between place value. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
