This game below is I-Spy-
So you choose one of the pictures to use below, pick an object and say "I spy something beginning with ..."
See if your child can find the object. This can also be played around the house. Giving your child lots of experiences to hear the initial sounds in words.
Another game to practice initial sounds is labeling things around the house by writing the letters, if your child can hear the initial sound eg 't' for television, they could write this on a piece of paper and put it next to the television. If your child can hear the sound but needs support writing, show the the soundmat for support (below or in you learning pack)
