KS3 - Plotting Graphs (Part 2)

Slides for introducing plotting graphs.

This is Part 2 - It builds directly on Part 1 to an x-axis that goes negative and shows the linear continuation into negative y, while the quadratic remains positive in terms of y.

Part 2 sees the students plot a linear and a quadratic function but only for positive values of x. I get them to do both on a single sheet of A4 graph paper.

Lots of “what do you notice”, “what’s the same; what’s different” opportunities.

Students enjoy this and it works well as a double maths (approx 2 hours) session. It went down a storm with a capable Year 8 class.

I feel there’s real value in them creating a graph from a blank piece of graph paper, from start to finish.
