Time — Victorian Year 4 Maths
am and pm time, finding durations and elapsed time, and converting between seconds, minutes, hours, days and weeks. Three subtopics and 60 questions with answers, aligned to VC2M4M03.
Time in Victorian Year 4
This topic is about reading and working with time. Students use am and pm to say which half of the day they mean, find how long events last by counting on from a start time to a finish time, and change between units of time such as minutes and hours.
The three subtopics below are am and pm time, duration and elapsed time, and converting units of time. Time is one of the 20 topics in Victorian Year 4 Maths and sits in the Measurement strand. All three come under Victorian Curriculum 2.0 code VC2M4M03. These skills lead on to 24-hour time and longer timetables in later years.

Time: common questions
What is the difference between am and pm?
am times run from midnight to midday, and pm times run from midday to midnight. Midday is written 12 pm and midnight is 12 am. A school day might start at 8:45 am and finish at 3:10 pm, so both halves of the day appear in one school day.
How do you work out elapsed time?
Count on in easy jumps rather than subtracting. From 9:35 to 11:10, jump 25 minutes to 10:00, then 1 hour to 11:00, then 10 minutes to 11:10: 1 hour 35 minutes in total. Subtracting the digits does not work, because an hour has 60 minutes, not 100.
How do you change hours into minutes?
Multiply by 60, because every hour has 60 minutes: 4 hours is \(4 \times 60 = 240\) minutes. For a mixed time, change the hours and add the extra minutes, so 1 hour 45 minutes is \(60 + 45 = 105\) minutes. To go the other way, divide by 60.
How can my child practise time at home?
Ask your child to read the clock at set moments of the day and say whether it is am or pm. Time real activities, such as a bath or a trip to the shops, and work out how long they took from the start and finish times. Bus and TV timetables make good practice too.
Which curriculum codes cover Time in Victorian Year 4?
All three subtopics come under Victorian Curriculum 2.0 code VC2M4M03, the Year 4 content on solving problems about how long things take, including am and pm times and changing between units of time.
