Pie Graphs on Netbooks

Thursday, 03 December 2009 | 0 Comments

Despite every Year 9 student having a laptop for a few weeks, the topics we’ve been covering haven’t lent themselves to full laptop lessons. To end the term, though, we’re reviewing graphs.

The worksheet below gives students some activities to complete using these two interactives from Shodor:

• Pie Chart and
• Circle Graph

The idea is to, with minimal instruction, allow the kids to develop an understanding of fractions, percentages, parts and angles as used to make pie (sector) graphs.

I used this with Year 9 today, and it went quite well (despite half the class being out for peer support with Yr 6 students). I answered many questions, but they were relevant questions about the next step rather than generic do all my work for me please type comments. Here’s a student work sample (PDF). We spent the whole 1 hour lesson on the activities, I think one student completely finished.

A couple of notes about the logistics – I provided the Word document (below) for the students to download, and to save their work to. I also provided links to the activities. To copy the graphs to their worksheet, they used the Windows 7 Snipping Tool.
