Memory

A novel twist on a classic children's game.

The problem

This exercise will help illustrate the different relationships that classes can have with each other.

The game is played much like the classic game Memory, that requires the participants to remember the location of two related cards. Unlike a traditional memory game, the cards will not be identical, but will rather be two related classes. These classes can be related in several ways:

• Inheritance
• Interfacing
• Inner Class
• Aggregation
• Association

Participants and props

This exercise is designed to involve the entire class. It will require several index cards, some tape.

The Cards: Association:

* Car - Driver
* Course - Instructor

Aggregation:

* Cell - Grid

Inheritance:

* Plant - Flower
* Animal - Bee

Interfacing:

* Comparable - Double
* Flushable - Toilet

Inner Class

* Linked List - Iterator

The script

Setup: The cards are scrambled, and then taped on the board in a grid. If the class is large, you may consider having the students break into teams of two or three.

Gameplay: Each student, in turn, is given the chance to select two cards to be flipped over. If the student believes that the two cards are a match, then they must identify the manner in which the two cards are related. If the student is correct, these cards are removed from the board and handed to that student. This is repeated until the grid is entirely removed. The person with the most cards wins.
