CCSS.Math.Content.6.EE.A

CCSS.Math.Content.6.EE.A is a cluster heading. These are the individual standards under it.

• CCSS.Math.Content.6.EE.A.1

  Write and evaluate numerical expressions involving whole-number exponents.

• CCSS.Math.Content.6.EE.A.2

  Write, read, and evaluate expressions in which letters stand for numbers.

• CCSS.Math.Content.6.EE.A.2a

  Write expressions that record operations with numbers and with letters standing for numbers.

• CCSS.Math.Content.6.EE.A.2b

  Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a singl...

• CCSS.Math.Content.6.EE.A.2c

  Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operati...

• CCSS.Math.Content.6.EE.A.3

  Apply the properties of operations to generate equivalent expressions.

• CCSS.Math.Content.6.EE.A.4

  Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them).

01

What Students Need to Do

Students translate words into algebraic expressions and evaluate them for given variable values. They apply order of operations and properties to rewrite expressions in equivalent forms.

02

What Mastery Looks Like

Students read, write, and evaluate expressions with variables, exponents, and grouping symbols. They use the distributive property and combine like terms to produce and justify equivalent expressions.

03

Common Misconceptions

Students may treat 3x as 3 + x or think x² means 2x. They may ignore grouping symbols, apply operations left to right, or distribute incorrectly.

04

How to Assess It

Use this exit ticket: Evaluate 3(2 + n) when n = 4, then rewrite 3(2 + n) as an equivalent expression and explain why.

1. 01

   Give pairs algebra tiles to model 3(x + 2), then rearrange the tiles to show 3x + 6.

2. 02

   Ask students to explain in writing why 4(x + 3) and 4x + 12 give the same value.

3. 03

   Play expression match with cards showing verbal phrases, algebraic expressions, and equivalent forms.

4. 04

   Use a phone plan with a monthly fee and per-text charge to write and evaluate an expression for different usage amounts.

• CCSS.Math.Content.5.NF.B.4

  Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

• CCSS.Math.Content.6.NS.C

  Apply and extend previous understandings of numbers to the system of rational numbers.

• CCSS.Math.Content.7.NS.A

  Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.

• CCSS.Math.Content.5.NF.B

  Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
