Pictogram

This week in maths R has been working on graphs and surveys. Here he is on my balcony counting the cars that pass the house.

Counting Cars

Here is the tally chart R made. You can download a copy at Sparklebox.

Next R made a pictogram using car pictures also available at Sparklebox. 

Car Colours pictogram

I asked R to interpret the graph which he did well, even telling me that white cars are most popular because they reflect the most heat and keep the people inside cool in the Australian sun.
