What you need to know E3 –L2 Read and write common fractions, for example halves, quarters, thirds, tenths. Understand what the top and bottom numbers represent. Understand that a unit fraction is one part of a whole divided into equal parts for example 1/3 , 1/10 . Understand that non-unit fractions are several equal parts of a whole, for example 3/4 represents three parts of something that has been divided into four equal parts, (¼ + ¼ + ¼ ). Understand that equivalent fractions look different but have the same value. Recognise and use equivalence, for example 2/4 = 5/10 = ½ , 6/6 = 1. To write one quantity as a fraction of another, put the first quantity on the top of the fraction, and the second quantity on the bottom. Know how to change fractions to equivalent fractions with a common denominator. Find fractions of quantities. Evaluate one number as a fraction of another. Use fractions to solve practical problems. Add and subtract using halves, thirds, quarters, fifths and tenths
