Times

Which times on a digital clock have a line of symmetry? Which look the same upside-down? You might like to try this investigation and find out!

Ten Green Bottles

Do you know the rhyme about ten green bottles hanging on a wall? If the first bottle fell at ten past five and the others fell down at 5 minute intervals, what time would the last bottle fall down?

Why do this problem?

This problem is one to use when relating time and distance and especially when looking at timetables and the $24$ hour clock. Timetables are tricky things and they sometimes need careful thinking to make sense of them. There are many conventions involved in their presentation and learners may need help in finding the meanings in them.

Key questions

Have you drawn a diagram of the buses on the road from A to B?

How many buses are on the road at $0600$?

How many buses are on the road at $0620$, $0640$, $0700$ and so on?

Do you understand how the $24$ hour clock works?

Possible extension

Learners could find out bus times from a local timetable and even make up their own problem about them.

Possible support

Suggest starting by drawing a picture all the coaches on the road at various times.
