24-hr timetables; calculate time intervals - Teaching Presentation _ Year 5

This presentation provides four days of teaching that cover the objectives:

• Calculate time intervals using the 24-hour clock.
• Read timetables and calculate time intervals using the 24-hour clock.
• Read timetables using the 24-hour clock.
• Calculate time intervals.
• Given a time delay, count on to find new train departure and arrival times.

It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.

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.

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?

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.

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.

This teaching is part of Hamilton’s Year 5 Measures and Data block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
