Workshop Sessions

Proportionality & Similar Figures: Why This Topic Matters

• First, each lesson itself draws on real-world applications, whether it's developing a pledge plan to raise money for charity (Patterns & Functions) or creating a geometry scavenger hunt (Polygons & Angles).
• Second, we have assembled online resources, where math teachers and experts from across the country have contributed their own ideas about how to make math more relevant. (See Links & Resources)
• Finally, each workshop features conversations with the Learner Teachers about a few practical ways that the math concepts being discussed in the program appear in daily life.
