Seventh Grade Geometry 5 - Circumference teaches students the formula for finding the circumference of a circle and use that information to solve problems. In addition, they will learn the relationship between the diameter and the circumference and how that information is the basis for pi. There is a title slide, focus slide, objective, essential question, vocabulary, vocabulary check, concept development, guided practice, checking for understanding, problem solving with a word problem, and a reward slide at the end. For best results, students should have white boards and dry erase markers. This lesson covers Common Core Standard 7.G.4.
