Tic Tac Toe is a GREAT game for young kids. They learn to take turns as well as accept winning and losing!
I use Tic Tac Toe in various ways to give a fun boost to letter, name, and number writing practice. It is a VERY quick go to, with ZERO prep. Once they know how to play the game, they can use the assigned letters or numbers to play. On the wider board on the second page, they can play using their names to get vital name writing practice. And of course, don't forget to use these for sight words!
These can be printed for consumable use, or laminated on cardstock for dry erase, I find that the additional step of erasing to play again is difficult for beginning kinders though.
Be sure to print on both sides to get double the use!
