Straight-line Graphs

Description

A planning idea for turning lessons on using graphs and gradients into practical activities to help pupils understand the concepts, in this secondary Key Stage 3 mathematics resource.

Maths teacher Kathryn Hurrell, at Comberton Village College, helps her lower ability Year 9 pupils understand straight-line graphs by turning the mathematical concept into a practical activity.

Kathryn gives groups of pupils some simple y=mx+c equations and they work out pairs of suitable coordinates and stand at that point within a large scale set of axes on the classroom carpet.

By doing this, they start to appreciate what their graph should look and feel like, and how its 'slope' changes with the different equations they've been given.

She explains that any classroom management issues this activity might raise, through pupils moving around the room, are outweighed by its value as a practical and effective lesson that they'll easily remember when they're thinking about graphs and gradients.
