**Title:** Can You Solve the Mystery of the Variable?

**Description:**
This lesson will help students master Algebra I standard 15: Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations [A-CED4]. The lesson will make the connection between isolating a guilty person in a “who-dun-it” with isolating a given variable in an equation. In addition, this lesson will involve students creating a list of procedures to use when solving for a given variable. At this time it is not necessary for students to know the formal names for the properties. It is important for students to understand the concepts and take part in creating a set of procedures for isolating a variable and solving equations.

**Title:** Solving Formulas for the Given Variable

**Description:**
This lesson will use the process of inverse operations to solve formulas for a given variable. Some formulas will not be recognized by the student. The actual formula is not important, but the variables are.
