Proportionality & Similar Figures: Why This Topic Matters

Why Do We Have to Learn This Stuff, Anyway?

Teachers hear this kind of question every day. The Missing Link offers some practical advice to help teachers answer these questions.

  • 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.

Some Everyday Ways to Use Proportionality & Similar Figures

Proportionality & Similar Figures helps students with two concepts fundamental to all mathematics: building their number sense and making intelligent numerical comparisons.

  • Drawing a map to scale — travelers
  • Doubling (or halving) a recipe — cooks
  • Enlarging a photograph or picture — designers; newspaper, Web and magazine editors
  • Calculating the unit rate of a product to decide which is a better buy — consumers
  • Remodeling a room — designers, builders, homeowners
  • Designing a building or a bridge — architects, engineers
  • Planting a garden — gardeners
  • Designing a banner — students
