Online picture graphs
Saturday, 12 February 2011
A worksheet to accompany the online tool Pictogram Graph (see on MathsLinks).
Two parts to this activity for a lower ability class:
- Take a class survey on transport methods to school, students record the results on the worksheet (digitally) and assign the symbols. The graph can then be created online, a screenshot taken and their graph pasted into the worksheet.
- Two more sets of data to complete two more picture graphs.
Whilst I thought this task would be straight forward, there was some good discussion with students about changing the scale.

Interesting – could you describe a little more please: What year level did you do this with? What sort of mathematical discussions occurred?

Sure, I used this with a low ability Year 8 class.
The discussions that I didn’t expect came from considering what scale to select. So, to represent ‘sales’ in the ticket sales question, how do you know which scale to select when it’s initially set at 1. Yes, a very low level question.
