Most preschool students learn through song and rhyme. As often as you can, sing the alphabet song with your child. Use the transition times such as between the end of dinner and evening family activities or while riding to the store in the car. Challenge your child to make up a rhyme using each letter. During bath time use washable bathtub markers to write letters while singing the alphabet song or making rhymes.
Place one cup of sugar on the bottom of a paper plate and encourage your child to replicate letters using her index finger. A small shake of the plate allows room for another letter construction. In lieu of writing letters with a pencil and paper, use the rest of her chocolate pudding from lunch and finger paint on a piece of thick paper or poster board. Encourage her to attempt to write her name while naming the letters aloud.
Use as many hands-on manipulative tools as possible. Purchase a set of magnetic refrigerator letters and play with her on the kitchen floor. Show her one of her favorite movie cases and ask her to build a word using the letters, while sounding them out, to spell a character or movie title. Create a set of personal flash cards using blank index cards that have a letter written on one side and a child-drawn image coinciding with the letter sound on the other.
Play a game of riddles or seek and search with your child to find real-world examples of letters you have discussed. When shopping at the grocery store, ask your child to find a box of cereal beginning with the letter "R" or find a letter "O" on an overhead aisle sign. Play an I Spy riddle with your child while going for a walk around the neighborhood. For example, when passing by the Smith home, mention that you see a letter that makes and "sss" sound and looks like a snake.
There are a vast number of games to reinforce the alphabet for students just learning and for those having some trouble. Use the computer to teach alphabet sounds, letter construction, and sight recognition through preschool and kindergarten games. Kaboose, Zoodles, Fisher Price, Play Kids Games and Starfall are only a few of the programs available for children. Allow your child to type letters, and even their name, in various font styles, sizes and colors in a word-processing document for extra practice.
