Can you create a story that would describe the movement of the man shown on these graphs? Use the interactivity to try out our ideas.

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its vertical and horizontal movement at each stage.

How far have these students walked by the time the teacher's car reaches them after their bus broke down?

How does the position of the line affect the equation of the line? What can you say about the equations of parallel lines?

Use the interactivity to move Mr Pearson and his dog. Can you move him so that the graph shows a curve?

If you have only 40 metres of fencing available, what is the maximum area of land you can fence off?

Position the lines so that they are perpendicular to each other. What can you say about the equations of perpendicular lines?

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects the distance it travels at each stage.

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its speed at each stage.

Charlie has created a mapping. Can you figure out what it does? What questions does it prompt you to ask?

Collect as many diamonds as you can by drawing three straight lines.

Investigate what happens to the equation of different lines when you translate them. Try to predict what will happen. Explain your findings.

Explore the relationship between simple linear functions and their graphs.

I took the graph y=4x+7 and performed four transformations. Can you find the order in which I could have carried out the transformations?

There is a particular value of x, and a value of y to go with it, which make all five expressions equal in value, can you find that x, y pair ?

Alf Coles writes about how he tries to create 'spaces for exploration' for the students in his classrooms.

Investigate what happens to the equations of different lines when you reflect them in one of the axes. Try to predict what will happen. Explain your findings.
