How to Evaluate Expressions the Easy Way | 6.EE.A.2 💚💜
In this video lesson we will learn what it means to evaluate. We will then evaluate algebraic expressions given the value of the unknown variable. We will review PEMDAS and order of operations. We will evaluate algebraic expressions involving exponents, negative coefficients, and multiple variables. Student practice is embedded in the lesson with a modeled exemplar solution.

Common Core Math Standards
6.EE.A.2 Write, read, and evaluate expressions in which letters stand for numbers.
6.EE.A.2.C Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
