I made little bingo game boards in my Microsoft Excel spreadsheet. For the Kindergartenerds I colored each square a different color(of course, each card will need to be different). I would call out a color and they would put a marker on that color. One the other side of my game board I put the color words. I would call out the color or show them a card with the color on it and they would put a marker on their board. The kids really enjoy this.
I made another bingo board and put some letters (capital & lower case together) in the squares then I would call out the corresponding animal we studied with that letter. The children would find the letter and mark it.
