To hold interest, we can "play" some game by challenging math learners to come up with any form of mathematical graaphics generated through maths expression plotted in a graph.

An example is shown below. A beautifully created diagram of a ........

fish with mouth wide opened, ready to absorb whatever equations that come along!

This type of game will arouse and sustain the learning of maths, and also serves to demonstrate the application of graphs.

Happy? :)
