In KS2 Maths as children advance to Year Five their knowledge of fractions will increase. By now they should know the values of different fractions and will be introduced to numerators and denominators, proper and improper fractions and mixed numbers.
Fractions denote numbers that are less than a unit. One way of writing these 'partial' numbers is by using a decimal point. These are called decimal numbers. An example would be 2.5. 2.5 as a fraction would be written as 21⁄2. 21⁄2 is a mixed number. Another way to write it would be 5⁄2 which is an improper fraction. Proper fractions have numerators which are lower than their denominators.
