Clock Hands make teaching time simple and best of all, very inexpensive for the whole classroom. Simply attach with a suction cup to your whiteboard, or use the supplied magnet to attach to a blackboard. Either way the hands are easy to view from the back of the classroom. Write the numbers on the white/black board and move the hands into the position needed with your index finger. Teacher's insert with teaching ideas and game are included. Grades 2+, Ages 7+.
