Suitable for Grades: 6th Grade, 7th Grade
CCSS: 6.EE.A.2.C, 7.EE.B.4.A
CCSS Description: 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.
Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
This worksheet is designed to help learners convert from sentences describing an algebraic calculation to an algebraic expression.
In section A, examples are given in each table as a guide, with the different types of language used for each operation.
Section B has a matching activity with expressions just using the letter m and the number 2.
