# Simplifying Expressions

Videos and practice problems for simplifying expressions and identifying equivalent expressions using the distributive property, other properties of operations and combining like terms. MGSE6.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. MGSE6.EE.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.) For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for. SWBAT apply the properties of operations IOT generate equivalent expressions and create visual models of equivalent expressions. SWBAT determine whether two expression are equivalent IOT generate an argument that justifies and explains the properties of operations.
