Good reading skills help children become good writers. The reverse is also true. When children learn to write well they internalize the conventions of the English language. Their understanding of English can then be applied to their reading experiences.
So how does writing begin? It begins with the alphabet. Teach your child the traditional alphabet song or just have her recite the alphabet. Always treat this as a game. Reciting the alphabet should be as fun as singing a song or reciting a favorite nursery rhyme.
