Class quiz
10 questions on Time. Students join with a name, you see everyone's score.
For Teachers
- Identify the hour hand and minute hand on an analog clock
- Read time to the hour and half hour on analog clocks
- Read time to 5-minute intervals on analog clocks
- Convert between analog and digital time representations
- Understand the difference between AM and PM
- • Counting by 5s up to 60
- • Understanding numbers 1-12
- • Basic addition and subtraction
- 1. What activities do you do at specific times each day?
- 2. Why do you think we have two different types of clocks (analog and digital)?
- 3. What would happen if clocks didn't exist? How would people know when to do things?
- 4. Can you think of places where you see clocks every day?
The hour changes when the minute hand passes 6 (30 minutes)
On digital clocks, the number after the colon goes up to 99
For Struggling Students:
- • Start with only hour times (o'clock) before adding minutes
- • Use color-coded hands (red for hour, blue for minute)
- • Practice counting by 5s with manipulatives before clock reading
For On-Level Students:
- • Read times to 5-minute intervals
- • Convert between analog and digital representations
- • Solve elapsed time problems within an hour
For Advanced Students:
- • Calculate elapsed time across hours
- • Work with 24-hour (military) time
- • Solve multi-step time word problems
- 1.MD.B.3 (CCSS.MATH.CONTENT.1.MD.B.3)

Definition
- Analog clocks have a round face with numbers 1-12 and two hands
- Digital clocks show time with numbers like 3:45
- The hour hand (short hand) points to the hour
- The minute hand (long hand) points to the minutes
- Some clocks have a second hand that moves quickly
- 1 hour = 60 minutes
- 1 minute = 60 seconds
- 1 day = 24 hours
Worked Examples
The hour hand points to 3. What hour is it?
Find the hour hand
The hour hand is the SHORT hand → Short hand identified
See where it points
It points directly at the number 3 → Points to 3
Read the hour
When the hour hand points to 3, the hour is 3 → 3 o'clock
Answer: It is 3 o'clock (3:00)
Common Mistakes
Confusing the hour and minute hands
Why it's wrong: Both hands look similar and move around the clock face.
Correct: Remember: the SHORT hand is for hours, the LONG hand is for minutes. Think 'S' for Short and Small numbers (1-12 hours).
Reading minutes as the number shown, not multiplied by 5
Why it's wrong: Students see the minute hand at 4 and say '4 minutes' instead of '20 minutes'.
Correct: Each number on the clock represents 5 minutes. Minute hand at 4 means minutes.
Saying the wrong hour when the hour hand is between numbers
Why it's wrong: When it's 7:45, the hour hand is close to 8, so students say 8:45.
Correct: The hour doesn't change until the minute hand reaches 12. If the hour hand hasn't passed the next number, use the smaller number.
Why It Matters
- School: Knowing when class starts and ends
- Transportation: Catching the bus or train on time
- Activities: Meeting friends, sports practice, appointments
- Cooking: Timing recipes and meals
- Sleep: Knowing bedtime and wake-up time
Real World Applications
School Schedule
Students need to read clocks to know when classes start and end.
Example:
If math class starts at 9:30 and lasts 45 minutes, it ends at 10:15.
Your science class starts at 2:15 and lasts for 50 minutes.
What time does science class end?
Step 1: Write the mathematical expression
Add 50 minutes to 2:15:
Catching Transportation
Buses and trains run on schedules, so reading time accurately is important.
Example:
If the bus comes at 8:20 and it takes 10 minutes to walk to the stop, you should leave by 8:10.
Your train leaves at 4:45. It takes 25 minutes to walk to the station.
What is the latest time you should leave home?
Step 1: Write the mathematical expression
Subtract 25 minutes from 4:45:
Key Takeaways
- 1Analog clocks have two hands: short (hour) and long (minute)
- 2Each number on a clock represents 5 minutes for the minute hand
- 31 hour = 60 minutes, 1 minute = 60 seconds
- 4AM is for morning (midnight to noon), PM is for afternoon and evening (noon to midnight)
- 5Digital clocks show hours:minutes (like 3:45)
Frequently Asked Questions
Why do clocks only show numbers 1-12 if there are 24 hours in a day?
What does 'o'clock' mean?
Why is the minute hand longer than the hour hand?
Glossary
- Hour hand
- The short hand on an analog clock that points to the hour
- Minute hand
- The long hand on an analog clock that points to the minutes
- Second hand
- The thin hand that moves quickly, counting 60 seconds per minute
- AM
- Ante meridiem - the time from midnight (12:00 AM) to just before noon
- PM
- Post meridiem - the time from noon (12:00 PM) to just before midnight
- Quarter past
- 15 minutes after the hour (e.g., quarter past 3 = 3:15)
