Use stencils to draw uppercase and lowercase letters on construction-paper cards. Cover the construction-paper cards with contact paper, and mix them up in a basket or bowl. While timing your preschooler for a minute or two, ask him to pair the uppercase letters with their lowercase counterparts. When time is up, look to see how many correct matches he has created. Reward him on a prize scale, such as hugs and kisses for one or two correct answers or a small toy for five correct answers. Play the game often so his "score" will improve.
Create or purchase a set of flash cards featuring each letter of the alphabet as well as a set of cards that display a picture of an item that begins with each letter. Lay the cards out on the floor or table in two separate groups to show where each letter and item card are positioned before turning them over. Place the alphabet cards in correct order to help your child remember the sequence, but the picture cards do not need to be in order. After you have placed all the cards face down, let your child turn over a letter card and then ask her to find the picture card that coordinates with the letter. Time the game to indicate that letter recognition should eventually come easily for your little one.
Help your child remember the letter you've studied for the day by writing a short, silly story with him. For instance, if the letter is B, start the story off with something like "There was a boy named (child's name) who loved the color blue. But he didn't like Brussels sprouts; his favorite food was brownies." Ask your little one to point out how many times you've used the letter once the story is finished, and time him as he does so to determine how keen his letter recognition is. Allow your child to illustrate the story with markers or crayons, and the two of you can frame it to display in his room.
Buy your child a frame for a shadowbox, along with craft supplies such as yarn, glue, ribbon and synthetic flowers. Gather a pile of old magazines and help your child cut out letters and pictures to use for the alphabet shadowbox. Remind your little one of the letter the two of you have been focusing on for the week, and time him for five minutes as he creates a collage in which this letter of the alphabet is the feature. When he's done putting the craft together, let him pretend to be a famous artist describing his work to you. Give him points each time he says a word beginning with the feature letter. Offer prizes based on how often he mentions the letter, such as a trip to the park for five words or the chance to choose what the family has for dinner for 10 words.
