Chris Rowland and Ryan Fredette

Background

Polymorphism Match-up

This exercise will help to establish the ideas surrounding polymorphism and inheritance.

You will need index cards with all the shapes listed below written on separate cards:

Triangle Parallelogram Trapezoid Rectangle Square Pentagon Octagon Oval Circle Sphere Cube Cylinder

Have the 5 students come to the front of the class, they will be representing the objects for each round.

The class will be playing the game as rows.

Each round the 5 volunteers will get the cards represented by the 5 objects on screen.

A class will appear at the top of the screen, if you know whether an object represented by a person is a subclass or not, raise your hand.

Correct answers get your row 1 point. Wrong answers are -1 point.

Repeat for each object in a round and for each round consecutively. The row with the most points gets the ultimate grand prize of self-satisfaction.

Flash version of powerpoint. Pause between each round.
