Step 4 Objective

Compare and order a mixed set of numbers or measurements with up to three decimal places.


What if pupils find this a barrier?

Encourage pupils to look at the value of the digit on the left.

Pupils may find it helps to read the numbers in words including the place value, e.g. reading 6.25 as 6 units, 2 tenths and 5 hundredths, which is smaller than 6.3 (6 units and 3 tenths).

Practise with situations that pupils are comfortable with, e.g. metres or money. Extend from two decimal places to three decimal places.

Write numbers on cards so that they can sort them, move them around, compare and discuss.
