Lesson Plan

Translate verbal descriptions into algebraic expressions using variables, and read algebraic expressions aloud or in words

Identify parts of an algebraic expression using precise mathematical terms: sum, term, product, factor, quotient, coefficient

View a sub-expression as a single entity at one level while recognizing its internal structure at another level

Evaluate algebraic expressions by substituting specific values for variables, using parentheses around substituted values and applying the conventional order of operations

Apply formulas from real-world contexts by substituting given values -- including fractions -- and evaluating the result

6.EE.A.2

6.EE.A.2 Write, read, and evaluate expressions in which letters stand for numbers.

a. Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation "Subtract y from 5" as 5 - y.

b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.

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 = s^3 and A = 6s^2 to find the volume and surface area of a cube with sides of length s = 1/2.
