Core concept: Mathematicians use analog and digital clocks to tell time on the hour.
Ask students:
Why is time important?
What would happen if we didn’t have clocks?
How would we know when to get up and go to sleep?
How do we use clocks to tell the time?
Explain that to play this game students will become human clocks, using their body to create different times on the hour.
Demonstrate how to stretch your arms up and out to the side to feel the position of the hour and minute hands.
Encourage students to rock from foot to foot while slowly chanting Tick, tock, tick, tock. I’m a ticking human clock. What time is it?
Call out a time. Students make that time with their arms showing the position of the hour and minute hands (see Figure 18).
