Initial sounds in words: Hearing the first sound in a word. Try to elongate the first sound, so the children can hear it better. Start with easy words that have s, c, t, o sounds at the start.
Blending: Sound out words and see if your child can blend them. Do an action and sound out one of the words in your sentence. Put your jacket and say "I'm putting on my j-a-ck-e-t". See if your child can blend the word.
