Singapore Math Level 2A & 2B – Unit 13: Time
This unit focuses on teaching students how to read clocks, understand time intervals, and solve problems related to time, including converting between hours and minutes. It introduces practical skills for time management and reinforces concepts of time through engaging exercises.
1. Look at the clock below. Fill in each box with the correct answer.
A clock has numbers from 1 to 12. Based on the position of the minute hand along these numbers, the time increases in multiples of 5. So tell us how the time is calculated in that case. The method is-
5×1=5
5×2=10
5×3=15
5×4=20
5×5=25
5×6=30
5×7=35
5×8=40
5×9=45
5×10=50
5×11=55
5×12=60
Then based on this, if we fill in the cells of the given figure, we get the following figure.
The time shown on the clock is 7.00 A.M.
What time is it? Write the correct minutes on the lines below (2-5).
Solution(2-5):
2. 5×4=20
3. 5×1=5
4. 5×9=45
5. 5×3=15
Write the correct time on the lines below (6-9).
Solution(6-9):
6. The Time is ten o’clock / 10:00
7. The Time is five-fifteen / 5:15
8. The Time is one-thirty / 1:30
9. The Time is twelve o’clock / 12:00
