## Year 3 maths: Pairs that make 100

When working out how many more to make a number up to 100 it is important not to mix up two different ways of doing it. Let’s take the question: ‘How many more is there from 45 to 100?’ One way of doing this is to add 5 to 45, making 50 and then counting […]

## Percentages and Fractions

The relationship between percentages and fractions is one that many children fail to grasp, yet it is essentially quite easy. What is harder, is understanding equivalence and that fractions of the same size can be written in different ways. 100% means 100 out of 100. It can written as a fraction 100/100 and is equivalent […]

## Written methods of subtraction

During the early years children are not expected to employ written methods to subtract numbers. The aim at this stage is to use mental methods and become really efficient with this.

We often presume that much of what young children have to do in maths is self evident and easily understood by them. However, often this is not the case, especially if children have missed some time or not had enough practice to consolidate their learning. Here we have a simple exercise to just check that […]
