Maths Year 5 Summer Measures and Data

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

24-hr timetables; calculate time intervals (suggested as 4 days)

Planning and Activities

Day 1 Teaching
Revise 24-hour clock times. Revise counting up on a time number line to calculate time intervals in the context of school lessons, e.g. from 10:45 to 11:35, 13:30 to 14:45, 11:50 to 12:35.
Group Activities
-- Calculate time intervals on the class timetable.
-- Calculate time intervals on the class timetable, then compare with lesson durations in a younger class.

Day 2 Teaching
Ask questions requiring simple interpretation of the Hogwarts Train Timetable, e.g. What time does the 08:45 reach Ottery St Catchpole? Convert 24-hour to 12-hour times and vice versa. Then ask questions requiring calculation of time intervals, e.g. How long does the 08:45 from Diagon Alley take to reach Ottery St Catchpole? Which is the fastest train between Kings Cross and Hogwarts?
Group Activities
-- Investigate journey times by interpreting a train timetable.

Day 3 Teaching
Use and interpret the timetable for the North Yorkshire Steam Railway. Practise writing 24-hour times as 12-hour times. Calculate time intervals and solve reasoning problems.
Group Activities
-- Plan itineraries using a real railway timetable.

Day 4 Teaching
Give fictitious train delay announcements, e.g. The 14:48 to Birmingham New Street is running approximately 37 minutes late as a result of sheep on the line near Worcester. Model counting up on a number line to find the new departure time. Repeat.
Group Activities
-- Use counting on on a number line as a strategy for adding a time duration to a start time.

Mastery: Reasoning and Problem-Solving

  • True or false?
    13:40 is twenty to two in the afternoon.
    Midnight is 00:00.
    Midday is 12:00 on the 24- hour clock.
    19:15 is quarter past 7 in the morning.
    1 hour after 15:00 is six o’clock pm.
  • Calculate how long it is between:
    13:40 and five to 5 in the afternoon.
    Quarter to midday and 17:23.
    Five past midnight and ten to midday.
  • If each bus is 40 minutes late, write its new arrival time.
    (i) Number 31 bus due at 12:55.
    (ii) Number 22 bus due at 13:04.
    (iii) Number 15 bus due at 14:44.
  • The number 4A bus arrived 27 minutes late at 00:14. What time was it due?

In-depth Investigation
Use the investigation described in the group activities for Day 3.
