Middle School Geometry--Grade 7--Lesson 2: Area and Circumference of Circles

This Grade 7 geometry lesson focuses on calculating the area and circumference of circles using the formulas \( A = \pi r^2 \) and \( C = 2\pi r \). Students explore the relationship between radius, diameter, and circumference, while reinforcing their understanding through coordinate geometry and real-world examples. The lesson is aligned to Common Core Standard CCSS.MATH.CONTENT.7.G.B.4 and emphasizes both conceptual understanding and procedural fluency. Students analyze circle diagrams, scale drawings, and apply formulas in problems involving circular structures such as the U.S. Capitol Rotunda and Pueblo Bonito kivas. Multimedia resources from Media4Math.com include clip art collections, instructional videos, and vocabulary definitions that support key concepts. Worked-out examples guide students through multi-step problems, and a comprehensive quiz with answer key provides opportunities for assessment and review.
