- It is morning. The analog clock below shows the current time. If the minute hand moves forward 2 positions (10 minutes), what time will it be?
Answer: 7:40 a.m.
The clock shows 7:30 a.m. Moving the minute hand forward 2 positions means adding 10 minutes (each position = 5 minutes). 7:30 + 10 minutes = 7:40 a.m. Choice B adds 20 minutes instead of 10. Choice C adds only 5 minutes (1 position). Choice D adds 30 minutes instead of 10.
- These times are all in the same afternoon: 3:05 p.m., 2:40 p.m., 3:40 p.m., and 3:15 p.m. Which time is the latest?
Answer: 3:40
These times are all in the same afternoon. The time 2:40 is before 3:00. Of 3:05, 3:15, and 3:40, the latest is 3:40 p.m.
- Jake arrives at the station at 3:25 p.m. What is the next train he can catch?
Answer: Train B departing at 3:35 p.m.
Jake arrives at 3:25 p.m., so he needs the first train that departs after that time. Train B at 3:35 p.m. is the earliest one still to come. Train A already departed at 3:20 p.m., before Jake arrived. Choices C and D depart later than needed, so they are not the next available train.
- The movie theater shows that a movie starts at 7:15 p.m. and ends at 8:50 p.m. How long is the movie?
Answer: 1 hour and 35 minutes
From 7:15 p.m. to 8:50 p.m.: First, 7:15 to 8:15 is 1 hour. Then 8:15 to 8:50 is 35 more minutes. Total: 1 hour 35 minutes. Choice A miscounts the minutes as 25. Choice C adds an extra 10 minutes. Choice D subtracts 20 minutes incorrectly.
- What time is half past 6?
Answer: 6:30
Half past 6 means 30 minutes after 6 o'clock, which is 6:30. 7:30 is half past 7, not half past 6. 6:15 is only 15 minutes after 6, which is a quarter past, not half past. 6:45 is 45 minutes after 6, which is three-quarters past, not half past.
- Marcus has soccer practice every Tuesday at 4:20 p.m. Today is Tuesday and he needs to leave his house 15 minutes before practice starts. At what time should Marcus leave his house?
Answer: 4:05 p.m.
Practice starts at 4:20 p.m. Marcus needs to leave 15 minutes before: 4:20 - 15 minutes = 4:05 p.m. Choice B adds 15 minutes instead of subtracting. Choice C subtracts only 5 minutes. Choice D subtracts only 10 minutes.
- The clock below shows when Sarah's piano lesson ended. Her lesson was 30 minutes long. What time did her piano lesson start?
Answer: 11:55 a.m.
The lesson ended at 12:25 p.m. and lasted 30 minutes. Working backwards: 12:25 - 30 minutes = 11:55 a.m. Choice B uses p.m. instead of a.m. and adds time. Choice C subtracts only 20 minutes instead of 30. Choice D incorrectly uses p.m. instead of a.m.
- Which time is half past 3?
Answer: 3:30
Half past 3 means 30 minutes after 3 o'clock, which is 3:30. Choice B (3:15) is quarter past 3, not half past. Choice C (3:45) is quarter to 4. Choice D (3:00) is exactly 3 o'clock, with no time added.
- The library closes at 6:00 p.m. It is currently 5:35 p.m. Lisa wants to check out books, which takes 10 minutes. How much time will be left when she finishes?
Answer: 15 minutes
From 5:35 to 6:00 is 25 minutes, and checking out books takes 10 minutes, so 25 minus 10 leaves 15 minutes. 5 minutes is too little time left over. 25 minutes is the total time before closing, not what's left after the task. 35 minutes would only make sense if the task added time instead of using it up.
- What time is half past 3?
Answer: 3:30
This question tests 2nd grade understanding of telling time to the nearest 5 minutes using analog clocks, including reading hour and minute hand positions (CCSS 2.MD.C.7: Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.). An analog clock has two hands: the short, thick hour hand points to the hour (or between hours as minutes pass), and the long, thin minute hand points to the minutes. To tell time: (1) Look at hour hand—which two numbers is it between? Use the smaller number (if between 3 and 4, it's 3 o'clock-something). (2) Look at minute hand—which number does it point to? Count by 5s from 12 to that number (if at 5, count: 5, 10, 15, 20, 25 = :25). (3) Combine: 3:25. Describe key times: When minute hand points at 12, it's o'clock (:00). At 3, it's :15 (quarter past). At 6, it's :30 (half past). At 9, it's :45 (quarter to next hour). In this problem, the question asks for the time that is half past 3, without a clock shown. To find the answer, know that half past means :30, so for 3 it's 3:30 (minute hand at 6, hour hand halfway to 4). Choice B is correct because half past 3 means 30 minutes after 3 o'clock which is 3:30 (minute hand at 6). This demonstrates accurate clock reading to nearest 5 minutes. Choice A represents vocabulary error (said half past 3 is 3:15 instead of 3:30). This error typically happens when students don't know time vocabulary. To help students: Use large demonstration clock with moveable hands. Teach hand identification: 'Short hand = hour (it takes hours to move), Long hand = minute (minutes move fast).' Practice hour hand position: show 3:00 (hour hand right at 3), then move minute hand to 6 (hour hand moves halfway to 4 for 3:30). Teach counting by 5s for minutes: number 1 on clock = :05 (skip count: 5), number 2 = :10 (skip count: 5, 10), and so on. Use rhyme: 'When minute hand points to 6, we say half past 3:00, that's 3:30—don't be tricked!' Practice key times: o'clock (:00, minute hand at 12), half past (:30, minute hand at 6), quarter past (:15, minute hand at 3), quarter to next hour (:45, minute hand at 9). Have students practice reading: 'Hour hand is between ___ and ___, so hour is ___. Minute hand points at ___, count by 5s: 5, 10, 15... = :___. Time is ___:___.' For drawing, remind: hour hand doesn't point directly at hour unless it's exactly o'clock. Connect to daily schedule: 'Recess is at 10:15. Let's read the clock at recess time.' Watch for: confusing which hand is which, not noticing hour hand moves gradually, miscounting by 5s, reading minute hand position as hour, forgetting :30 is half past (not :15), not combining both hands to get full time.
- Clock 1 shows 2:10 p.m. and Clock 2 shows 3:25 p.m. How much time passed between the time on Clock 1 and the time on Clock 2?
Answer: 1 hour and 15 minutes
From 2:10 p.m. to 3:25 p.m. is 1 hour and 15 minutes. Choice B, 1 hour and 25 minutes, is 10 minutes too long. Choice C, 45 minutes, is far too short for the time that passed. Choice D, 1 hour and 35 minutes, is 20 minutes too long.
- It was 2:00. Now it is 2:30. How many minutes passed?
Answer: 30 minutes
From 2:00 to 2:30, the minute hand moves from the 12 to the 6. Count by 5s: 5, 10, 15, 20, 25, 30. So 30 minutes passed. 60 minutes would be a whole hour, from 2:00 to 3:00.
