### 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.
