The various resources listed below are aligned to the same standard, (6EE04) taken from the CCSM (Common Core Standards For Mathematics) as the Expressions and equations Worksheet shown above.

*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. Reason about and solve one-variable equations and inequalities. *

- Simplifying Expressions (2 of 2) e.g. 3xy + 6xy + 3yz - 2yz - xy = 8xy + yz
