What We Did Today:
Students defined variables by giving them a name and assigning them a value or expression, used variables within Evaluation Blocks and described a situation where using variables as substitutions for values or expressions is more efficient. Students took Lesson 5 notes and completed Stage 5, which is available on Google Classroom.
Vocabulary:
- Define - Associate a descriptive name with a value.
- Immutable - the value can't be changed during the execution of a program. Think about it this way: saying x = 50, and then x = x + 1 might make sense in Javascript, but it's impossible in Algebra.
- Variable - A reference to a value or expression that can be used repeatedly throughout a program.
