What This Standard Means
What Students Need to Do
- Students name parts of expressions as terms, coefficients, factors, sums, differences, products, or quotients. They also treat a grouped part as one mathematical object.
What Mastery Looks Like
- In 4(x + 3), the student identifies 4 and x + 3 as factors and x + 3 as a sum. The student can describe the whole expression as a product.
Common Misconceptions
- Students may call every number a coefficient, including a constant term. They may ignore parentheses and name x and 3 as separate factors of 4(x + 3).
How to Assess It
- Display 5a + 2(b - 1). Ask students to identify the terms, coefficients, factors, and one grouped expression treated as a single entity.

Ways to Teach It
Give students expression strips to cut, bracket, and label as terms, factors, coefficients, sums, products, and quotients.
Ask students to describe 3(8 + y) in two ways, including how 8 + y acts as one entity.
Play expression vocabulary bingo using examples that students must match to term, factor, coefficient, sum, product, or quotient.
Label the parts of a cost expression that combines a flat fee with a price per item.
