  • Grades: 6-8
This in-demand collection of lessons explores proportionality, proportional relationships, and proportional reasoning, acknowledging that the ability to reason proportionally is at the forefront of the middle school mathematics curriculum.

The lessons support teachers in beginning to think of proportionality as the "big idea" that connects across all strands.

Each lesson features carefully detailed teaching notes, three sets of question types to ask students as they progress through the lesson, and reproducible student recording sheets. In addition, the lessons are correlated to the Common Core State Standards for Mathematics.
