There are well over 200 different activities here. You will be able to create your own diagrams and change them using the mouse and see the effect these changes have on the graphs and on the algebra involved.

graphsSelect one of the three units at the top right: coordinates, lines or curves, then choose from the topics available.
Use the coloured grid grid to select a task. Move down the grid to change the task to something a little demanding mathematically, move left or right to change a small aspect of the task. you are here shows where you are.

A large variety of aspects of graphs is covered, from plotting straight lines, quadratic, cubic, reciprocal and trigonometrical curves to solving equations. At higher level you can investigate transformations of graphs and more unusual curves such as those of exponential functions and 4th degree polynomials.
