Evaluate Algebraic Expressions Using Substitution (Exponents 2 of 2)

TEKS Math: 6.7.A

(A) Generate equivalent numerical expressions using order of operations, including whole number exponents and prime factorization

AU Math: ACMNA134

(Y6) Explore the use of brackets and order of operations to write number sentences (ACMNA134)

CCSS Math: 6.EE.2.C

6.EE.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). For example, use the formulas V = s3 and A = 6 s2 to find the volume and surface area of a cube with sides of length s = 1/2.

This algebra and functions lesson focuses on evaluating expressions by using the order of operations. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students substitute the given value of each variable into the expression. Then, they evaluate the expression by determining which operation to perform first (using PEMDAS) and repeating the order until no more operations can be performed. Finally, they compute the value and interpret the answer. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items and 12 flashcards for the order of operations.
