Quiz Answer Key
1.
The two main hands are the hour hand (shorter) and the minute hand (longer). The hour hand indicates the current hour, while the minute hand indicates the minutes past the hour.
2.
Each number on a clock face represents 5 minutes.
3.
The hour is determined by the number the hour hand has just passed.
4.
"O'clock" means the time is exactly at the hour, with the minute hand pointing at the 12. "Half past" means 30 minutes past the hour, with the minute hand pointing at the 6.
5.
"Quarter past" means 15 minutes past the hour, with the minute hand pointing at the 3.
6.
If the minute hand is pointing at the 9, it indicates 45 minutes past the hour.
7.
There are 15 minutes in a quarter of an hour.
8.
You cannot tell if the time is AM or PM just by looking at an analog clock. You need additional context or a digital clock that displays AM or PM.
9.
The time is 10:10.
10.
If the minute hand is pointing at the 6, it could be half past any hour (e.g., 2:30, 7:30).
Essay Questions
1.
Explain the relationship between the movement of the hour and minute hand on a clock. How do they work together to show the time accurately?

Telling Time FAQ
What are the two main hands on a clock and what do they tell us?
A clock has two main hands: the hour hand and the minute hand. The hour hand is shorter and points to the current hour. The minute hand is longer and points to the minutes past the hour.
How many minutes does each number on the clock face represent?
Each number on the clock face represents five minutes.
How do you know what hour it is if the hour hand is between two numbers?
If the hour hand is between two numbers, the hour is the number the hour hand has just passed. For instance, if the hour hand is between the 2 and the 3, it is currently between 2:00 and 3:00.
What's the difference between "o'clock" and "half past"?
"O'clock" means the time is exactly at the hour, with the minute hand pointing at the 12. For example, 3 o’clock would have the hour hand pointing directly at the 3 and the minute hand pointing at the 12.
"Half past" means 30 minutes past the hour, with the minute hand pointing at the 6. For instance, half-past 7 would have the minute hand pointing at the 6, and the hour hand pointing halfway between the 7 and the 8.
What does "quarter past" the hour mean?
"Quarter past" means 15 minutes past the hour, with the minute hand pointing at the 3.
What time is it when the minute hand is pointing at the 9?
When the minute hand is pointing at the 9, it indicates 45 minutes past the hour, or 15 minutes to the next hour. You could also call this “quarter to” the next hour.
How many minutes are in a quarter of an hour?
There are 15 minutes in a quarter of an hour.
Can you tell if it's AM or PM just by looking at an analog clock?
No, you can't tell if it's AM or PM just by looking at an analog clock. You would need additional information, such as whether it is light or dark outside, or a digital clock that shows AM or PM.
Main Themes:
Components of an Analog Clock: The sources consistently highlight the key components of an analog clock – the hour hand, the minute hand, and the numbered clock face.
Reading the Hour: All sources explain how to read the hour based on the position of the shorter hour hand. They emphasize that if the hour hand is between two numbers, the hour is the number the hand has just passed.
Reading the Minutes: The sources detail that each number on the clock face represents five minutes. They explain common minute hand positions like "o'clock" (pointing at 12), "half past" (pointing at 6), "quarter past" (pointing at 3), and "quarter to" (pointing at 9).
AM/PM Distinction: The sources make it clear that analog clocks do not inherently indicate AM or PM. They state that additional context is required to determine whether the time is morning or afternoon.
Most Important Ideas/Facts:
Relationship between Hour and Minute Hands: The "Telling Time Study Guide" stresses the connection between the hour and minute hand movements. The minute hand completes a full circle every hour, while the hour hand moves incrementally to the next number. This synchronized movement is crucial for accurate timekeeping.
Importance of Telling Time: The study guide also emphasizes the significance of time-telling as a life skill. It impacts daily scheduling, punctuality, and personal organization.
Analog vs. Digital Clocks: The study guide explores the pros and cons of each type of clock. Analog clocks offer a visual representation of time progression, while digital clocks provide a more precise and direct reading.
