Rich tasks for this chapter - page 197
- These are problem solving open-ended questions that require students to investigate time. The tasks can be given at the start of a topic and done as the students gain enough knowledge to complete them, inserted into a topic at an appropriate place, or given as homework, or extension.
- Clocking your day
- Testing times

1. Clocking your day
2. Testing times
- You could make up some more relevant statements for students to test.
Students may need help to design their experiments and it would be a good idea to ask them to write down what they are going to do and show it to you before starting, to avoid time being wasted in unproductive experiments. If students need reminding about surveys you can use NZCM Connecting all Strands 3A Chapter 20 page 329.
Students who wish to record their results using graphs may need to revise this using NZCM Connecting all Strands 3A Chapter 19 page 311.
Solving time problems - page 198
- Solve problems involving time, including adding times and finding the duration of events given the start and end times.

Teacher notes
- Some students have difficulty working with time because it is not metric. Practice at changing minutes to seconds, hours to minutes etc may be needed first.
- Using real life examples that are relevant to your students is a good way of getting them engaged. You could make up some of your own questions such as
- How long is it until school finishes today?
- How many hours of maths do we do each week?
- I want to go to the chemist at lunchtime. If it takes me 3 minutes to walk to my car and… . Will I have time to get there and back before school starts again after lunch?
Timetables - page 203
- Read timetables and answer questions related to them.

Teacher notes
- Timetables in paper form are often too complex for students at this level.
- It is most engaging if students work with timetables that are relevant to their lives. It is best if you bring some in for them to look at and also show them some online. Some links have been supplied for you to use for this purpose but you might find some more relevant ones for your particular students.
