Papers are covered with contact paper so it doesn't get ripped up.
Here is how to play. Your child says "GO!" and you start moving the white paper (with the hole in it) around the poster very fast. Your child says "STOP!" and you stop at a letter. Either YOU say the letter/sound, or if your child already knows the letter then let him say it.
Let me just say that this game is rigged. You only stop at the letters you want to stop at. This way you can teach the letters you need to, or review the letters that you want to. When my kids learned a letter and knew it they got to put a star on that letter! This is the way that all 3 of my children learned their letters.
Here is a video I made to explain the game better. I played this game with Hannah before she turned 2 (in the video she is 3 1/2). It's just a fun Stop & Go game!
