Learning Goal
Part of: Apply and extend previous understandings of arithmetic to algebraic expressions — 3 of 4 cluster items
Apply the properties of operations to generate equivalent expressions
**6.EE.A.3**: Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6(4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

What you'll learn
- Apply the distributive property to expand expressions: rewrite a(b + c) as ab + ac and a(b + c + d) as ab + ac + ad
- Apply the distributive property in reverse to factor expressions: rewrite ab + ac as a(b + c) by identifying the common factor
- Combine like terms by recognizing that variables with the same letter and exponent can be added: simplify y + y + y to 3y
