Understanding Fractions

In Key stage 1 children will learn the basics about fraction e.g

At this stage they will also be taught about the numerator and denominator and what they represent. I would strongly recommend this is briefly revisited in KS2, as even if they have not forgotten, they may not appreciate how helpful this information can be.

The denominator is the number at the bottom of the fraction and represents the number of equal parts in a whole.

The numerator is the number at the top of the fraction and represents the number of parts you have.

From KS1 they should be familiar with this concept, although they will have dealt mainly with non-unitary fraction, it is important that they are able to apply this understanding to more complex non-unitary fractions. e.g.

A good way to practise this understanding in to simply make, divide and shade different shape, to correspond with different fraction. It is also really important that the child appreciate that all parts must be equal. Using a ruler to measure and divide equally is great, although a fair degree of inaccuracy should be expected. Folding is also a good way to estimate equal part.

Another good exercise is to use square or geometric paper to mark out shapes and colour in to match different fraction. e.g.
