Cut out the 28 rainbow boxes and the picture boxes. The children sound out the words and practice blending the sounds together until they know the word then they match the picture to it. I have included a couple of words that include a blend. The blend sounds are grouped together to help them sound out the word. I would introduce the activity at teacher table with a small group, them show them whole group how they can do it with a partner in a pocket chart as a literacy station. If they finish early, they can write the words they matched on a white board.
