What This Standard Means
What Students Need to Do
- Students translate verbal descriptions into expressions that use numbers, letters, operations, and exponents. They read expressions by identifying terms, factors, coefficients, and operation order. They substitute values for letters and evaluate accurately.
What Mastery Looks Like
- Students correctly write expressions from words and explain what each number, variable, term, and factor represents. They substitute given values and calculate accurately using exponents and order of operations.
Common Misconceptions
- Students may treat 3x as 3 + x or think x always means multiplication. They may reverse phrases such as “five less than n,” combine unlike terms, or ignore order of operations after substituting.
How to Assess It
- Use this exit ticket: Write an expression for “four less than three times n,” name its terms, then find its value when n = 6.

Ways to Teach It
Give pairs variable cards and operation tiles to build an expression from “five less than twice n,” then swap and interpret.
Ask students to explain in writing why 4x + 3 and 4(x + 3) do not describe the same calculation.
Play expression match: students pair verbal phrases, algebraic expressions, and values for a given variable, then justify each match.
Use a phone plan with a fixed fee and per-gigabyte charge, then write and evaluate an expression for monthly cost.
