It sounds as if the school is using JP actions (so possibly JP order of introducing the sounds)
1. s, a, t, i, p, n
2. ck, e, h, r, m, d
3. g, o, u, l, f, b
4. ai, j, oa, ie, ee, or
5. z, w, ng, v, short oo, long oo
6. y, x, ch, sh, voiced th, unvoiced th
7. qu, ou, oi, ue, er, ar
We taught 5 sounds a week and usually covered all 42 sounds by Christmas
Once the first set of sounds have been taught children can read words and by the end of set 2 children can start books (but of course that depends on whether individual are able to read the words)
