Online ABC games have a double function. They teach children the basics of using a computer as well as the fundamentals of the alphabet. Being comfortable with a keyboard and PC is also an important ingredient to a child's future success. Games online are also interactive---with bright colors and sounds that can help a child to retain what they've learned. Visit the alphabet page on Starfall.com and have children click on the brightly colored ABC blocks. They will hear a pronunciation of the letter in a child's voice and see the uppercase and lowercase versions of it. Visit the Internet 4 Classrooms site and get a list of "Pre-K Alphabet Resources" that will engage children while they become more familiar with their ABCs.
Certain letters can give children a hard time. Focus on those letters through their own games. Play the "Sneaky Snake" game, as listed on Gayle's Preschool Rainbow, with kids to help them say "s" correctly. Have children make their own "snakes" by sticking round, white stickers to a piece of construction paper. Tell them the snake can twist any way they like. Have them decorate the snake in different colors or with glitter pens. After they are done, talk about the hissing sound that snakes make, have them dance like a snake to music, and then have them sound out the letter "s" in different sentences that use the word "snake."
Gayle's Preschool Rainbow also has a matching game that will teach children their uppercase and lowercase letters; it's called "File Folder Letters." This game requires some preparation by the teacher, but can be used over and over again. Write the letters of the alphabet on file folders, one letter per folder. Laminate the front of the folder with contact paper. Make a lowercase and uppercase version of every letter out of construction paper. Laminate each letter with contact paper. Put hook-and-loop fasteners above each letter on the folder and on the back of all construction paper letters. Have the children spend a week matching the uppercase letters to their folder counterparts. Then spend the next week having them match the lowercase letters to the folders.
