Video Learning Notes

In this lesson, students learned to determine the area of composite figures by breaking them into simpler shapes such as rectangles, triangles, trapezoids, and parts of circles. They practiced calculating each area using appropriate formulas and summing these to find total areas. The lesson also covered finding lateral and total surface areas of three-dimensional shapes by analyzing their nets. Students developed problem-solving skills by applying these concepts to real-world problems and explaining their reasoning clearly.

Learning Goals

• Calculate the area of composite figures made up of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles.
• Solve problems involving lateral and total surface area of rectangular prisms, rectangular pyramids, triangular prisms, and triangular pyramids by determining the area of their nets.
