Goal 1: Use equations to solve realworld problems:
1) define useful variables
2) write an equation that matches the situation
3) solve, and
4) answer the question (all lessons)

Goal 2: Solve equations using a variety of techniques to isolate the variable (22, 23, 24)
Things to keep in mind are:
· Only do steps that keep the two sides equal!
· Simplify each side before solving, when helpful: combine like terms that are on the SAME side,
use the Distributive Property, etc.
· Use inverse operations on BOTH sides to undo steps in the equation
· Undo the operations using the Order of Operations backwards (“SADMEG”)
Goal 3: Check a solution by substituting into the original equation (22, 23, 24)
Goal 4: Correctly interpret whether an equation has one solution, no solution, or is an identity (all real numbers are solutions) (24)
