The Set 1 sounds are the first phonics sounds children need to learn, and these form the building blocks for all word decoding.
Before a child can start to read, they need to learn to:
+ Say the sound that is represented by each letter or groups of letters. These are called ‘speed sounds’.
+ Know how to blend the sounds together in a word to read it e.g. c-a-t = cat. This is called ‘sound-blending’.
