How many hours are in a day? Why are there only 12 numbers on the clock?

There are 24 hours in a day. You only need 12 numbers because the clock goes around two times each day.

Show the time 9:00 on an analog demonstration clock. What parts can you name on the clock? What time does the clock show?

The numbers on the clock show the hours. The shorter hand is the hour hand and the longer hand is the minute hand. The time is 9 o’clock.

Show 2:30 on a demonstration analog clock. What time is shown on the clock? Is there a zero on the clock? Explain how you know where to start counting the minutes.

The time is 2:30. There is no zero on the clock because 12 is like zero. You start counting the minutes at the top, at 12.

Why do people sometimes say half past 2 for 2:30?

There are 60 minutes in an hour. 30 minutes is one-half of 60 minutes.

Where would you place the hands on a clock to show 10:30?

The hour hand points between 10 and 11. The minute hand points to the 6.

How many minutes are in 1 hour? Does each number on the clock represent 1 minute?

There are 60 minutes in 1 hour. No, each number on the clock represents 5 minutes.

Show the time 1:50 on the analog demonstration clock. Is the time 1:10? Explain.

No, the minute hand is pointing to the 10. You count by 5s to the number 10 to find the minutes: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. The time is 1:50.

Explain where you would draw the hands to show 7:17.

The hour is 7, so the hour hand goes between 7 and 8. For the minute hand, count to the nearest 5: 1 is 5 minutes, 2 is 10 minutes, and 3 is 15 minutes. 17 is 2 dashes past 15, so count 2 dashes past the number 3 and draw the minute hand.

Would you get the same answer if you started the minute hand at 12 and just counted 17 dashes? Explain.

Yes, counting 17 dashes ends at the same place on the clock. Each number represents 5, so counting by 5s to the nearest 5 is quicker and easier than counting by 1s.

Show 12:38 on the analog demonstration clock. Explain how to find the time on the clock.

The hour hand is between 12 and 1, so the hour is 12. The minute hand is pointing to 3 dashes past 7. Count by 5s to 7: 5, 10, 15, 20, 25, 30, 35. Count on 3: 35, 36, 37, 38. The time is 12:38.
