By the time a student reaches Kindergarten, they know how to play tic-tac-toe. Well, instead of using Xs and Ox, why not use the letters of the alphabet?
At the beginning, one student can use the capital version, and one can use the lower case.
As they learn more of the letters, you can review the letter of the week, and the letter from last week.
Later in the year, they can choose which letter they prefer.
Plus, as they write it, you can make a rule that they have to pronounce it as they write it. (Ex. b = buh).
