In this activity, students will create three different representations of the same logic. This ICA has $100$ points, with each deliverable being worth a percentage of those points.

Scenario

You are creating a calculator to help you determine how much lemonade you can make with the quantities of the ingredients you have. Our recipe for one serving of lemonade is shown below.

Lemonade recipe

For $1$ serving of $240$ ml $($that is$,$ about $1$ cup$)$

$190$ ml water

$50$ ml lemon juice concentrate

$80$ grams sugar $($about $3$ ounces$)$

$1$ disposable cup

$3$ ice cubes

The general idea here is that our calculator will take, as input, the amount of lemon juice and the amount of sugar we have on hand. We will then be able to determine how many servings we can create with that.

For this activity, we$$ll assume an infinite amount of water, ice, and cups. But, if we were really budgeting for a lemonade stand, we would need to think about those things too.

The calculator will always respond with the whole number of servings that are possible. We are not interested in preparing half a serving.
