Fractions, Decimals and Percentages
Fractions, decimals and percentages are all forms for expressing parts of a whole and each can be represented in any of the three forms. For example, the fraction ½ can be represented as a decimal (0.5) or as a percentage (50%).
Children use fractions such as ½ in their everyday language from an early age, i.e. they are 4½ years old, or they ate ½ an apple. This continues on to finding ¼, ½ and ¾ of shapes, then of an hour when they learn to tell the time to the ¼ hour. As your child progresses through KS2, fractions, decimals and percentages are introduced within the 4 basic operations (addition, subtraction, multiplication and division) and as a way to handle data and calculate probability.

I've written a summary sheet for fractions/decimals/percentages, mainly so parents have a document that gives the terms referred to with fractions etc. If can you check I have the right methods included, and I can update the Word document if necessary. Thanks.
