### 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.
