It's a Bingo game, well, like a Bingo game. It's to practice Kindergarten sight words. However, I included a blank one so you can add your own words. I use the blank one and laminate it for my 2nd grader's spelling words. I just write on it with permanent marker so they don't rub off every time he puts a tile over it but it is also removable with lemon oil or another dry erase marker drawn over it.
