Uphill and Downhill


In this feature we start by challenging you to play a game in which you need to identify the equations of straight line graphs. You can then move on to consider the properties of quadratics and cubics...

Diamond Collector

Age 11 to 16
Challenge Level Yellow star
Collect as many diamonds as you can by drawing three straight lines.

Quadratic Matching

Age 14 to 16
Challenge Level Yellow star
Can you match each graph to one of the statements?

Curve Hunter

Age 14 to 18
Challenge Level Yellow star
This problem challenges you to sketch curves with different properties.

Exploring Cubic Functions

Age 14 to 18
Challenge Level Yellow starYellow star
Quadratic graphs are very familiar, but what patterns can you explore with cubics?

Curve Fitter

Age 14 to 18
ShortChallenge Level Yellow starYellow star
This problem challenges you to find cubic equations which satisfy different conditions.
