Creating and naming variables: Lead the students to create meaningful names for their variables.
* What would be a unique and clear name for the variable that will keep track of the number of times Player A wins?
* Student suggestions may be: ‘PAW’, PlayerA’, ‘AButtonPress’, ‘AButtonCount’, ‘PlayerAWins’...
* Student suggestions may be: ``PAW``, ``PlayerA``, ``AButtonPress``, ``AButtonCount``, ``PlayerAWins``...
* Discuss why (or why not) different suggestions make clear what value the variable will hold. In general, variable names should clearly describe what type of information they hold.
In MakeCode, from the Variables menu, make and name these three variables: `PlayerAWins`, `PlayerBWins`, `PlayersTie`.
