Grades 6-8;
7 day unit - 48 pages;

In this unit, students explore the relationship between the areas of the squares on the sides of a triangle. The investigations develop a visual model for the abstract equation a2 + b2 = c2. Students then use the conceptual understanding developed in the activities to apply the relationship in problem-solving situations. Includes a CD with video help for each activity, as well as PDFs to facilitate printing and use on interactive boards.
