Step 4 Objective

Extend written methods to column addition and subtraction of numbers involving decimals.


What if pupils find this a barrier?

Ask pupils to bring in some old receipts, tear off the total part and pass the receipt to the pupil beside them to find the total. Can they do it on the receipt or do they need to lay it out differently?

For guidance on addition and subtraction with decimal notation refer to the document 'The National Numeracy Strategy: Teaching written calculations – guidance for teachers at Key Stages 1 and 2' (QCA/99/486) pp. 35–36.
