The Six Faces of Garbage

Sixth graders compute the surface area. In this surface area activity students are given a set of problems to calculate. They compute the surface area of cubes and rectangular boxes.

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

Students identify and use appropriate formulas to find surface areas of solid figures, practice using formula sheet to solve textbook problems, construct solid figures of given surface area using TABS+ software program, and use Internet...

How do you find the area if an object has more than four sides? Learners view an interesting video to learn how to determine the surface areas of rectangular prisms and pyramids. They see how to draw two-dimensional nets of the figures...

The lateral surface area of a cone. Hmmm, what does that mean? Oh, it means the part you see if the cone was sitting on a flat surface, so it does not include the base. But if you want to include the base then it would be finding the...

Build boxes using unit cubes to compare surface area and volume. The group performs multiple experiments to determine properties of volume, such as if it makes a difference which order the dimensions are multiplied in. Extensive...

Wrap up a lesson on surface area with a useful video. Pupils learn how to find the surface area of triangular and trapezoidal prisms. They watch a video to see an example for each type of prism.

Geometry.... sweet! Using sugar cubes, learners build rectangular prisms of different sizes and shapes. They glue them together and assess volume. Then they color the outer sides to visualize and compute surface area. To make a visceral...
