# Percentages (Year 6)

In KS2 Maths children will come to understand percentages as proportions of whole numbers. In Year Six children should be confident when converting decimal numbers into percentages, and vice versa. They should also be more familiar with the values of fractions as percentages, knowing that a third is approximately 33% for example. They should also be able to work out the percentage values of fractions they are unfamiliar with.

Percentages are proportions of whole numbers. You will probably have come across adults talking about a 5% pay rise or 10% inflation for example. But what does this actually mean? Well, 5% is the same as one twentieth so a 5% pay rise means an extra 5p in every £1. But 10% is the same as one tenth so 10% inflation means that prices have gone up by 10p in every £1!
