Type: Lesson/Unit Plan

Overview:

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.

8) Demonstrate that programs require known starting values that may need to be updated appropriately during the execution of programs.

Examples: Set initial value of a variable, updating variables.

Evidence Of Student Attainment:
Students will:
  • demonstrate that programs require known starting values that may need to be updated appropriately during the execution of programs.
Teacher Vocabulary:

Skills:
Students are able to:
  • explain a scenario in which starting value is important to a program.
Understanding:
Students understand that:
  • programs require known starting values that may need to be updated appropriately during the execution of programs.
