### 2.1 Writing Equations

Standard(s):

• N.Q.A.1: Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graph and data displays
• N.Q.A.2: Define appropriate quantities for the purpose of descriptive modeling.
• N.Q.A.3: Choose a level of accuracy appropriate to limitations on measurement when reporting quantities

Essential Question:
