Planning tool

Students:

• tell the time accurately on an analogue or digital clock or watch
• convert between 12- and 24-hour representations
• identify which states, territories and neighbouring countries are within the same time zone as theirs
• calculate the elapsed time between two events
• can read and interpret various timetables
• will use their knowledge of fractional parts to represent duration of time
• will use digital tools to investigate time zones.

Some students may:

• confuse the hands of an analogue clock or lack familiarity with analogue clocks.
• believe that they subtract the times as normal numbers and do not understand that minutes and hours are different units when working with the clock-time system (i.e. use base 10 not base 60).
• misunderstand the vocabulary of ‘o’clock’, ‘to’ and ‘past’ as there can be cultural differences in how the time is expressed.
• do incorrect conversions from 12- to 24-hour time, and vice versa, with the error being that they are not taking am and pm into consideration.
• not realise that when using the 24-hour clock, midnight can be shown as 0000 hours or 2400 hours depending on the context.
• have difficulty determining how long it takes to get from one place to another.
• have difficulty reading a timetable and understanding what the times represent.

The Learning from home activities are designed to be used flexibly by teachers, parents and carers, as well as the students themselves. They can be used in a number of ways including to consolidate and extend learning done at school or for home schooling.

Learning intention

• We are learning to interpret the time in analogue and digital form.
• We are learning to understand time zones in the context of Australia and its neighbours.
• We are learning to calculate the duration between two times.
• We are learning to explore how to calculate elapsed time.
• We are learning to use a calculator for time calculations.

Why are we learning about this?

If we understand different time zones around the world and how to effectively read and calculate time intervals we can work efficiently and use the right data in our globalised world! 

What to do

Task 1: Timeline

A timeline is a visual way to describe events in chronological order.

1. Develop a timeline to describe events that have taken place over 24 hours.

Task 2: Year 8 timetable

• Refer to your Year 8 timetable to answer the following questions in your book.
• Attach a copy of your timetable in your book.
  1. Calculate how much time you spend in class each day.
  2. How much time is spent doing English each week?
  3. How much time is spent doing Maths each week?
  4. How much time is spent doing Science each week?

Task 3: Time zones within Australia

• You have family in Perth (WA), Adelaide (SA) and Sydney (NSW).
• Your family lives in a different state or territory and wants to arrange a video call to connect with the other three families. Choose a time and work out the local time for each location so that the families can connect.

1. Record the information in a table:

 2. What effect does daylight saving have on the times of each state and territory?

Success criteria

• I can accurately tell the time on an analogue and digital clock.
• I can convert between 12- and 24-hour time.
• I can calculate the elapsed time between two events.
• I can identify different time zones for the states, territories and countries neighbouring Australia.
