In Phase 2, letters and their sounds are introduced one at a time. A set of letters is taught each week, in the following sequence:
Set 1: s, a, t, p
Set 2: i, n, m, d
Set 3: g, o, c, k
Set 4: ck, e, u, r
Set 5: h, b, f, ff, l, ll, ss
As soon as each set of letters is introduced, children will be encouraged to use their knowledge of the letter sounds to blend and sound out words. For example, they will learn to blend the sounds s-a-t to make the word sat. They will also start learning to segment words. For example, they might be asked to find the letter sounds that make the word tap from a small selection of magnetic letters.
