One of the most important pre-reading skills children need to learn is rhyming.
Playing with language is fun and increases children's ability to pronounce and hear the similarities yet differences in words.
Interactive word play can be part of everyday conversations while bathing, getting dressed, going outside, waiting in lines or offices, driving, shopping and/or picking up toys to put away.
Making up words that rhyme with each other is lots of fun, too. Write them down and invent meanings for them.
