EXECUTIVE SUMMARY

Objective

Teach how to read a graph in a Cartesian Plane.

Goals

Students should become comfortable following a path on a graph and understand why the graph increases, decreases,

changes direction and what are points of flex, vertices and infinity.

Solution

Use a game on an iPad or a tablet which will allow a user to follow a graph kinesthetically and gradually build

understanding of the underlying concept.

Project Outline

Create a game using processing development platform. The game will do following:

1. Display a graph in a Cartesian plane

2. Display a stick man at origin, as a user's avatar.

3. Initiate sensors on the device. The aim of the game is to physically follow the line of the graph by increasing or

decreasing the distance between a user and a solid object (I.e. a wall)

4. Make the stick man move by sensing the movement of the user. Whilst holding the device, the user needs to walk

toward or away from the wall, reducing or increasing the distance between the wall and the phone, respectively.

5. The distance will be plotted in a different colour than the drawn graph in the same Cartesian Plane on the device.

6. The walking pace will determine the angle of the rise of the graph.

As students become confident, more difficult graphs will be displayed. The difficulty will be rated by rating the

function plotting the graph.
