Lesson Plan: Surface Areas of Composite Solids Mathematics • 7th Grade
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to find the surface area of a composite solid using the formulas for lateral and total surface areas of a single solid.
Objectives
Students will be able to
- find the surface areas of composite solids where two solids have been joined together,
- find the surface areas of composite solids where one solid has been removed from another,
- solve real-world problems by finding the surface areas of composite solids.
Prerequisites
Students should already be familiar with
- finding areas of 2D shapes:
- squares,
- rectangles,
- parallelograms,
- triangles,
- trapezoids,
- kites,
- circles,
- finding the areas of composite 2D shapes.
