== Definition ==

Polymorphism is having one class take multiple different forms of objects. This allows it to reference itself and objects of other classes easily.

== Is-a ==
This is a rule that checks to see if you are allowed to use polymorphism on the class in reference to another. For example car is-a drivable so drivable is able to do what a car can do,however drivable is-not-a car so car cannot do what drivable can.

== The Game ==
Split the group into 4 groups of players.
This game is going to be played by the teacher (or whoever is directing the learning exercise to give a topic (a broad topic is best). For example "Living Things" now every group has to come up with a thing that inherits from "Living Thing" and then another thing that inherits from that etc. Make a list of 5 things .However if any groups have the same thing inherited than that point is not counted for any team that has it.
An example five things would be...

Topic:Living Things

Mammal

Platypus

Heart

Cell

Atom

Now if another team had

Topic:Living Things

Animal

Mammal

Primate

Human

Woman

The point mammal would be discounted for both teams.

Also any point that is not a valid inheritance is obviously discounted. The group with the most points after 5 rounds wins.

The number of groups , things inherited , and rounds could change based on how many people there are this is just a recomendation. It also needs to be played with groups of 3+ because groups of 2 would always tie.
