Maths Year 5/6 Spring Time and Data

Each unit has everything you need to teach a set of related skills and concepts.

Time and timetables (suggested as 2 days)

Planning and Activities

Day 1
Model using a timeline to find the interval between two times. Children write two times with a difference of 1 hour 25 minutes, including 24-hour times across noon and midnight.
Group Activities: T with Y5
Y5 -- Find possible start and finish times of films. Or, interpret a TV schedule to find a number of programmes with a total duration less than 9 hours.
Y6 -- Interpret a TV schedule to find a number of programmes with a total duration less than 9 hours. Some children will investigate the amount of TV time devoted to news.

Day 2
Children convert the 24-hour times on a timetable to 12 hour o’clock times, and say if times are morning or afternoon/evening. Model calculating time intervals using Frog to count up from one time to another.
Further Teaching with Y6
Display the timetable of trains from Thurso. Discuss how to calculate how long particular parts of the journey take.
Group Activities: T with Y6
Use the in-depth problem-solving investigation ‘Digits of Time’ as today’s group activity.
Or, use these activities:
Y5 -- Read a 24-hour train timetable and answer questions about it. Or, calculate lengths of TV programmes.
Y6 -- Read a train timetable: draw timeline jottings to help calculate time intervals or find journeys with set durations.

Mastery: Reasoning and Problem-Solving


  • Each of these train times is given using 24-hour clock. Write the times as analogue times in words.
    13:40 to London.
    14:45 to Bristol.
    15:13 to Newcastle.
    16:05 to Birmingham.
    17:35 to Chester.
  • Calculate the time interval between each pair of times:
    13:40 and five to 5 in the afternoon.
    Quarter to midday and 17:23.
    Five past midnight and ten to midday.
  • True or false?
    Half an hour after quarter to midnight is 01:15.
    16:25 is half an hour before 5 to 5.
    00:30 is half past midday.
    20 past 3 in the afternoon is 15 minutes before 15:35


  • Here is the time each child goes to sleep. Find out what time they each wake up if the first two sleep 9 hours and the second two sleep 9.5 hours.
    Amit: asleep at 22:00
    Anja: asleep at 21:45
    Sunil: asleep at 21:55
    Asha: asleep at 22:30
  • Which of these times would not change if you were using the 24-hour clock?
    3 o’clock in the morning
    Quarter to 2 after lunch
    Twenty past midday.
    Now write any times that will change using the 24-hour clock.

In-depth investigation: Digits of Time
Children find out how many times the digit 9 is used on the 24-hour digital clock between noon and midnight.

Extra Support

Time to Time
Converting times from am/pm to the 24-hour clock and vice versa. Begin to say how long to the next hour.
