This lesson will help illustrate how variables can make programs more powerful by allowing values to change while the code is running. You don't always know what a value is going to be before you begin your program. Sometimes, values change while your code is running. This lesson will illustrate how code with changing values can be helpful.
Students will be able to:
- identify areas where they can use variables to modify quantities during runtime.
- examine code to find places where variables can be substituted for specific values.
