6th Grade CMP3 Lesson Plan - Variables and Patterns - Equations Intro

Write, read, and evaluate expressions in which letters stand for numbers.

Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions 𝘺 + 𝘺 + 𝘺 and 3𝘺 are equivalent because they name the same number regardless of which number 𝘺 stands for.

Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
