Telling Time — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. If art class starts at 1:00 and lasts 30 minutes, it ends at 1:30.
Starting at 1:00 and adding the 30 minutes the class lasts brings the time to 1:30, since the hour stays the same.
2. The school bell rings at 8:15 AM.
School begins in the morning, and morning hours before noon are labeled AM. So the school bell at 8:15 happens at 8:15 AM.
3. If a movie starts at 6:00 PM and lasts 2 hours, it ends at 8:00 PM.
Adding 2 hours to 6:00 PM moves the hour count from 6 to 8 while staying in the evening, so the movie ends at 8:00 PM.
4. 15 minutes after 3:30 is 3:45.
Add 15 minutes to the 30 minutes already past 3:00: 30 + 15 = 45. The hour stays at 3, giving 3:45.
5. Dinner at 6:30 in the evening is 6:30 PM.
Evening hours fall after noon, and any time after noon is labeled PM. So dinner in the evening at 6:30 is 6:30 PM.
6. If you wake up at 7:00 AM and it takes 30 minutes to get ready, you are ready at 7:30 AM.
Adding the 30 minutes of getting ready to the wake-up time of 7:00 AM keeps the hour the same and brings the time to 7:30 AM.
7. One hour before 5:00 PM is 4:00 PM.
Counting back 1 hour from 5:00 PM lowers the hour by 1 and stays in the afternoon, giving 4:00 PM.
8. The number before the colon on a digital clock tells the hour.
On a digital clock the colon splits the time into two parts: the left number names the current hour, and the right number tells the minutes past it.
9. If math class is from 9:00 to 10:00, it lasts 1 hour.
From 9:00 to 10:00 the hour number goes up by exactly 1, so the class is 1 hour long (60 minutes).
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Sunrise at 6:00
→ 6:00 AM
7:45 AM
Dinner at 6:00
→ 6:00 PM
6:00 AM
Brushing teeth before bed at 8:30
→ 8:30 PM
8:30 PM
Walking to school at 7:45
→ 7:45 AM
6:00 PM
Sunrise and walking to school happen in the morning before noon (AM). Dinner and brushing teeth at bedtime happen after noon in the evening (PM).
