Maths Year 5/6 Summer Measures, Shape, Data

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

It’s time! (suggested as 2 days)

Planning and Activities

Day 1
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:
Y5/Y6 -- Plan itineraries using a railway timetable.

Day 2
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 on using a number line to find the new departure time. Repeat for different delay scenarios.
Group Activities:
Use the ‘Annoying clock’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
Y5 -- Use counting on using a number line as a strategy for adding a time duration to a start time.
Y6 -- Game adding hours and minutes, aiming to finish as close as possible to midnight.

You Will Need

  • ‘North Yorkshire Steam Railway timetable’ (see resources)
  • Internet access
  • Whiteboards and pens
  • A3 paper
  • 1–6 dice

Short Mental Workouts

Day 1
Read the 24-hour clock

Day 2
Units of time


Day 1
Y5: Interpret a fictional timetable, including reading times and calculating durations.
Y6: Interpret a fictional timetable, including calculating elapsed times.

Day 2
Y5/Y6: Given start times and an elapsed time, find journey end times.

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?
