Hints and Tips

Here 12- and 24- hour clocks are introduced to help read timetables etc.

The most valuable experiences are those involving real timetables that have significance for your child such as bus timetables or leisure centre opening hours.

Essential Prior Knowledge

Activity

With your child, collect a selection of timetables and advertisements with opening hours.

These can be local timetables or from somewhere your child would like to go, they can be bus, train, plane or anything. 

Ask:

·         Is the place open every day of the week?

·         How are the times written?

·         Which times are shown on the 12-clock?

·         Which times are shown on the 24-hour clock?

·         Why?

·         Are the different types suitable for different purposes?

Remind your child of the notation of am and pm times.

Looking at the timetables for 12-hour clocks, discuss the information shown. Explain the abbreviations “arr” and “dep” and ask questions such as “How long does the number __ bus stay in __?” and “How long does it take to travel from __ to __?”

Ask your child to move the hands on a geared clock face to show the durations. Encourage him/her to find the durations by counting on rather than calculating. Move on to include am and pm times.

Ask your child questions, such as, ”If you were on the bus for 18 minutes, where might you have got on and off?

Talk to your child about the 24-hour clock. Take some 12-hour clock times and turn them into 24-hour clock times, and vice versa.

Using the timetables with 24-hour times, discuss the information shown. Ask questions such as “How long does the number __ bus stay in __?” and “How long does it take to travel from __ to __?”

Ask your child to work out, from both 12- and 24-hour timetables, different journeys  they might take to arrive at different places, for various appointments and activities.

Project Idea

You could ask your child to plan an outing to a place of interest, using public transport planning arrival times and opening times of places he/she would like to visit.

You could also add a budget too.
