Why are some spellings shown as later or rarer?
The main spellings are the ones children meet in Reception to Year 2. The later ones, such as the ch in
chef, come up in older years or in a few special words, so the sound tiles only mix them in when they are
part of the word.
Why does a sound sometimes play as a short word?
Sounds that need several letters to say, such as the ai in rain, are recorded as the sound itself. Tap a
sound on this chart to hear exactly what the sound tiles play.
Is this the same as Letters and Sounds?
It follows the same ideas, with the sounds grouped the way Letters and Sounds teaches them. It is our own
chart, built from the sounds the app plays, so it only lists spellings the app can show.
