Finding Areas and Perimeters

Mrs. Mae guides students through a math lesson focused on calculating areas of various shapes, including playgrounds, patios, and walls, while excluding certain sections like sandboxes, fountains, and doorways. The lesson includes a review test of Chapter 13 concepts and concludes with story problems and homework assignments. Students are encouraged to follow along and practice the calculations, with a focus on understanding the process of finding areas and perimeters.
