Here's a taster:

Fill in tables for y = x, y = x + 1,
y = x + 2.
· Draw the graphs on the same axes.
· Write down what you notice.
· Repeat for y = x, y = 2x, y = 3x.
· Repeat for y = 2x, y = 2x + 1, y = 2x + 2.
· Try to use the words steepness and parallel in
your observations.
· Look at where the graphs cross the y axis (the y
intercept).

A geat presentation, taking you through the meanings and examples of gradients and intercepts of straight kine graphs.  Finishing with armchair gymnastics, brilliant!
