Review letter sounds and recognition with flashcards. One side of the card has a picture, while the other side has the corresponding beginning letter. For example, "A" is for apple. As your child becomes familiar with identifying the letters, add a challenge by having him say the sounds instead of the actual letters. For example, saying /a/ instead of "A."
Incorporate basic sight words into the flashcards (i.e. "in," "to," and "cat"). Use the Dolch list of words for kindergarten to make the cards. The Dolch list is a list of commonly used "service words" found in books, magazines, newspapers, etc.
Integrate reading practice into games. Many board games including phonological skills. For example, Monopoly Junior involves reading the Chance cards, while Boggle Jr. instructs players to create words out of presented letters. Any game that incorporates reading or letter identification is an effective reading intervention.
Read with your child. This is one of the most effective interventions to develop and strengthen reading skills. Make a daily plan to interactively read with your child. As you read, ask questions about the story. Exposure to literature enhances vocabulary.
