A hands-on way to teach your students about different angles.
Use these angle clappers to interactively show the different angles and their properties. They take a bit of constructing, but they’re well worth it when they are done.
The angle symbols are separate from the angle clapper, but all you need to do is cut them out and put a brass brad through the clapper board and the clapper. You then have a moving arm that represents the angle written on the board. The clapper arms have been labeled so you can easily match up the angles.
