In this video from Annenberg Learner’s Learning Math, carpenter Norm Abram of This Old House illustrates the concept of slope and relationships in house construction. The accompanying classroom activity helps students develop meaning for slope by building a slide, discussing slope in daily life, and understanding slope as a ratio of height/length. Students also learn about a career that uses the principles of slope and, as an extension, gather data that might be of use in a future lesson on slope as proportion.
