Read to your son each day. Your little boy will benefit from repeatedly hearing not only how a word is pronounced, but how individual letters sound as you read. If you find it difficult to sit down and read with your child, consider scheduling a family reading time each day. Don't be afraid to schedule reading at an unconventional time, such as after school or before breakfast. While many families enjoy reading together at night, this doesn't work for everyone. Write your designated reading time on your calendar so each family member knows when it's time to get together and read.
Review new vocabulary words with your son. Choose words from a book you're reading together, words you saw on the back of a cereal box or just words your child thinks sound interesting. Make a short list with the words and practice saying each word together at least once a day. Say each letter in the word before you state the entire word. Make sure your child pronounces each syllable correctly and help him if he struggles to remember how a certain letter sounds.
Provide your son with a variety of books and magazines that may spark his interest. If your son loves cars, for example, pick up a couple of children's books about cars. If your son prefers nature, buy a nature magazine. Leave books throughout the house so your son can read at his leisure if he sees something he likes.
