Use the responses to the hinge question to guide children to one of three levels of discussion.

🩺 One or other facet is likely to be seen to more important, and you'll probably have to encourage children to make the data representation exercise their own.

Add up what each thing costs

Plan what happens during the day and work out a cost for each.

Draw energy bars for the day.

🔎 Start diagnostic and exploratory discussions using thoughts like these:

A cost box can show what each thing uses.

Put the cost boxes in order to show when.

Total the cost boxes.

🧭 starting to explore

🩺 Children will be more willing to devise alternatives and consider a wider range of ways of representing the information.

Start from what the people in the house do.

Work out the total for what each person does. Then add them up.

Draw a plan for the day.

🔎 Start diagnostic and exploratory discussions using thoughts like these::

A set of cost boxes draw by time of day could show demand.

You could divide the day up by what was happening in the home.

A timeline would be a good start.

🧭 exploring a little deeper

🩺 Children draw on other data representing exercises and discuss both facets and how they can best be shown.

We'll need to add all the kilowatt-hours together.

Work out what each thing costs from how long it's on and its power.

Start with a timeline for the day.

🔎 Start diagnostic and exploratory discussions using thoughts like these:

You'll need a set of cost boxes, one per activity. The add up the contributions.

Maybe a cost box per thing would be easier to keep track of.

It'd be useful to add up the total for all the cost boxes.
