Simple Maze Game

Place in mathematics curriculum:

This activity can be used to:

• introduce the Cartesian coordinate system
• practice students' point plotting skills
• practice students' graph reading skills
• motivate the concept of slope

This activity allows the user to practice their point plotting skills by having them move a robot through a mine field to a target location. Moves are accomplished by specifying the coordinates of the new location. In order to win, the path must not cross a mine. This activity would work well in groups of two for about thirty minutes if you use the exploration questions and fifteen minutes otherwise.

Preparations for this activity:

• answer the question "How do you find distance?"
• discuss distance, positive coordinates, integers etc
