Activities in this teaching pack include differentiated worksheets to practise adding different three digit numbers and ones supported by the use of number lines to record the addition steps that result when counting to the nearest multiple of one hundred and ten.

The interactive presentation gets the children to explore how to use number lines to illustrate and record how to add different pairs of three digit numbers and ones.

This lesson is part of a maths scheme of work to get the children to practise using mental and written calculation methods to add three digit numbers with one, two and three digit numbers including informal and formal columnar techniques with exchange between place value.
