In Between TimeTask 25 ... Years 4  10SummaryAs time passes, both the minute hand and the hour hand move. Yet in the hour from each o'clock the minute hand repeats all its positions. It is the hour hand which has to journey for 12 hours before it begins to repeat its positions. This task first uses a thirty minute difference (embodying the idea of half of the hourly minute hand journey) to establish that students understand:

IcebergA task is the tip of a learning iceberg. There is always more to a task than is recorded on the card. 
The key to this task is the 'travel' relationships between the minute and hour hands.

Note: This investigation has been included in Maths At Home. In this form it has fresh context and purpose and, in some cases, additional resources. Maths At Home activity plans encourage independent investigation through guided 'homework', or, for the teacher, can be an outline of a class investigation.

Whole Class InvestigationTasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. 
First collect clocks for the classroom. The students can help with this by bringing some from home, and you could also visit garage sales and junk shops. Perhaps you could pool the clocks already in the school. You will need at least one clock per pair, but the lesson could work with one between four. To build your whole class investigation, follow the sequence of challenges on the card. Encourage discussion, explanation and justification. At this stage In Between Time does not have a matching lesson on Maths300. 
Is it in Maths With Attitude?Maths With Attitude is a set of handson learning kits available from Years 310 which structure the use of tasks and whole class investigations into a week by week planner. 
In Between Time is not in any MWA kit. However it can be used to enrich the Chance Measurement kit at Years 3/4 and Years 7/8.
