CCSS.Math.Content.HSA-SSE.A

CCSS.Math.Content.HSA-SSE.A is a cluster heading. These are the individual standards under it.

• CCSS.Math.Content.HSA-SSE.A.1

  Interpret expressions that represent a quantity in terms of its context

• CCSS.Math.Content.HSA-SSE.A.1a

  Interpret parts of an expression, such as terms, factors, and coefficients.

• CCSS.Math.Content.HSA-SSE.A.1b

  Interpret complicated expressions by viewing one or more of their parts as a single entity.

• CCSS.Math.Content.HSA-SSE.A.2

  Use the structure of an expression to identify ways to rewrite it.

01

What Students Need to Do

Students identify terms, factors, coefficients, exponents, and grouped subexpressions. They explain what each part represents and rewrite expressions in useful equivalent forms.

02

What Mastery Looks Like

Students can break a complex expression into meaningful parts and name the role of each part. They can rewrite it to reveal a useful feature, such as factors, zeros, or growth rate.

03

Common Misconceptions

Students often confuse terms with factors or treat a negative sign as separate from its term. They may distribute exponents incorrectly, cancel across addition, or assume expressions that look different cannot be equivalent.

04

How to Assess It

Give students 3(x + 2)^2 - 5. Ask them to label its main parts and explain exactly what quantity is being squared.

1. 01

   Build expressions with algebra tiles, then have students identify terms, factors, coefficients, and grouped quantities in each model.

2. 02

   Ask students to explain how x^2 - 9 and (x - 3)(x + 3) reveal different information.

3. 03

   Run a card sort matching equivalent expanded, factored, and grouped expressions, with students justifying every match.

4. 04

   Use 500(1.04)^t to identify the starting amount, growth factor, rate, and role of time in a savings account. In
