Middle School Geometry--Grade 6--Lesson 1: Area of Polygons

This middle school geometry lesson introduces students to the concept of finding the area of polygons by composing and decomposing shapes into rectangles and triangles. Aligned with Common Core Standard CCSS.MATH.CONTENT.6.G.A.1, the lesson provides clear instruction and visual models to help students break down complex figures, apply area formulas, and reason about shape structure. Through worked-out examples, students learn to calculate the area of irregular figures using a variety of strategies, including decomposition, coordinate geometry, and triangle-based constructions.

The lesson makes extensive use of Media4Math.com multimedia resources to support vocabulary development and conceptual understanding, including definitions of polygons, right triangles, and geometric formulas. Students begin with a structured warm-up, explore eight step-by-step examples during instruction, and reinforce learning through a review section with real-world and coordinate-based problems. A 10-question interactive quiz and answer key are included for practice and assessment. This lesson is ideal for classroom instruction, small group intervention, or independent study.
