To create excitement and awareness:

Variation or proportionality deals mainly with seeing a connection between two variables. The simplest real life example to start off the lesson on direct variation is the scenario of parents increasing or decreasing their allowances - their consumption patterns will increase or decrease in like manner.Therefore we can conclude that consumption pattern/s vary/ies directly with allowance/s obtained. Formal definitions will follow subsequently.
