TEKS Math: 6.7.D

(D) Generate equivalent expressions using the properties of operations: inverse, identity, commutative, associative, and distributive properties.

CCSS Math: 6.EE.3

6.EE.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.
