Encourage your child to stretch his oral and written vocabulary, as well as his acquaintance with colors. Get a box of crayons and pull one out. Take turns rhyming a word and a color, using the crayon that you pull from the box as your cue. For example, a red crayon might elicit "red bed" and a yellow one may inspire "yellow fellow." For boxes with several shades of the same color, read the crayon's label to make your rhymes. The rhymes can be as silly as you like; even nonsense or pretend words can increase your child's recognition of letter sounds, called phonemic awareness. Write down each rhyme, and then ask your child to illustrate them.
