Straight-Line Graphs
This video resource from Teachers TV features mathematics teacher Kathryn Hurrell as she delivers a lesson on straight line graphs to a lower ability Year Nine class at Comberton Village College. Using a set of axis drawn on the floor of the classroom, practical activities help students to understand the concepts of gradient and intercept. Groups of students are given some simple y=mx+c equations, from which they work out pairs of coordinates and they then stand at those points. By doing this, they start to appreciate what their graph should look like and how its 'slope' changes with the different equations they have been given
