2.1 - 2.6: Unit on Proportional Reasoning, Rates, Ratios and Percents

Begins with an intro to Cross-Multiplying (including a clear presentation of why it works). Then builds fluency with rates. Teaches how to set up rate problems quickly so the proper units cancel. Applies this concept to percent questions, laying the groundwork for Lesson 2.5. A mix of whole-class discussion and small-group practice.
