Original Prompt7th grade area of polygons introduction lesson and worksheets (whole numbers when possible)
This lesson focuses on calculating the area of various 2D shapes, specifically rectangles, triangles, and parallelograms. Students will learn to apply specific formulas to determine area using whole number dimensions. The lesson includes a worked example for finding the area of a triangle, where students will engage in guided practice to identify dimensions and plug them into the formula. The session also provides practice problems for calculating the areas of rectangles and parallelograms, along with a metacognitive check for students to assess their confidence. Additionally, students will tackle problems involving triangles and composite figures while reflecting on the relationships between the areas of different shapes.
