Learning Goal
Part of: Apply and extend previous understandings of arithmetic to algebraic expressions — 4 of 4 cluster items
Identify when two expressions are equivalent
**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). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for.

What you'll learn
- State what it means for two expressions to be equivalent: they name the same number for every value substituted for the variable
- Use substitution of multiple values to test whether two expressions appear to be equivalent
- Confirm equivalence by simplifying both expressions using properties of operations (distributive property, combining like terms)
