Musical Alphabet is a simple game to help younger children learn the alphabet and alphabetical order. If there are ten students in the group, then give them the first ten letters of the alphabet on flash cards.
If there are 20 students in the group, then give them the first 20 letters, and so on. Play some music while the children walk around the classroom. When the music stops, the children must arrange themselves in the order of the alphabet.
As the children become more confident, give them random letters. So, if there are 15 students, give them any 15 cards, not necessarily the first 15. When they arrange themselves in order, there are some letters of the alphabet missing but they can still arrange the letters in the correct order.
