Teaching time will be much easier using the Day/Night Teacher® Classroom Teaching Clock. Move the minute hand with either the dial which is located on the back of the clock, or by using the knob support on the minute hand. The sun and moon wheel turns as the clock hands move in a 12 hour period to illustrate day and night. The minute hand is blue, to match the minute ticks, the hour hand is orange to match the hour ticks.
