I like to use these for review games with my students. Each individual (or you can also make teams/groups) gets a board with 1 set of A, B, C & D. The child/team has to decide which one they think is the correct answer, clip clothes pin on that and when it is time just holds up. As a teacher, you can quickly survey the room to see where your class is at. Lots of other uses for them! Let me know what you think of.
