### Transcript

• 1. How to Tell Time
Ms. Leonard’s Class
October 27, 2009
• 2. What a Clock Looks Like
• Clocks have two hands, a big hand and a small hand.
• 3. The big hand tells time in minutes.
• 4. The small hand tells time in hours.
• What Do the Numerals Mean?
• A clock has twelve numerals, 1-12.
• 5. Each one represents five minutes.
• 6. Twelve numerals x 5 minutes means that there are 60 minutes in one hour.
• Past or to the Hour?
• If the minute hand is in the red region, it means that time is being told past the hour (the hour just started).
• 7. If the minute hand is in the green region, time is being told to the hour (a new hour is approaching).
• How the Clock Works
The clock can be split into quarters and halves.
If the big hand points at the 6, 30 minutes has passed (half of 60).
If the big hand points at the 3, 15 minutes has passed (half of 30).
30 minutes has passed
15 minutes has passed
• 8. How the Clock Works Continued
If the big hand is at the 9, 45 minutes has passed (30 minutes + 15 more since it’s another quarter hour).
This youtube clip walks you through how to tell time and has many examples. Check it out!
• 10. Lets Look at Some Examples…
Example 1:
The big hand is pointing at the 1, meaning 5 minutes has passed. The little hand is on the 12 meaning the hour is 12 o’clock. The time is then 12:05.
• 11. Examples Cont.
Example 2:
The big hand is pointing at the 12 meaning it is on the hour, 0 minutes have passed. The little hand is on the 2, meaning the hour 2 o’clock. The time is 2:00.
• 12. Examples Cont.
Example 3:
The big hand is just about on the 1 meaning a little under 5 minutes has passed. The small hand is on the 5 meaning the hour is 5 o’clock. The time is roughly 5:04.
• 13. Examples Cont.
Example 4:
The big hand is on the 5 meaning that 25 minutes has passed (count by 5’s until you reach numeral 5). The little hand is on 10 meaning the hour is 10 o’clock. The time is 10:25.
• 14. Final Example
Example 5:
The big hand is just a little past the 5 meaning a little more than 25 minutes has passed (count by 5’s until you reach numeral 5). The little hand is on the 9 meaning the hour is 9 o’clock. The time is roughly 9:26.
