## The Volume of Prisms and Pyramids

The purpose of this lesson is to expand the knowledge of using the volume formulas. Students will use volume formulas to calculate volume of prisms and pyramids as well as calculate missing dimensions. To be able to use and explain formulas in order to solve problems is a major work of level E Geometry.

Students will use many previously learned skills in this lesson in order to calculate volume and calculate the missing dimensions when given volume. Students will need to have an understanding of substitution and solving equations for a variable. Students will also need to be familiar with converting units of measure.

During this lesson, students will work through problems involving filling a swimming pool and converting attic space into a finished room. These activities will allow students to see how this knowledge could be a benefit in their own lives outside of the classroom.

## Things That Are Round

The purpose of this lesson is to expand student's knowledge of using the volume formulas. Students will use volume formulas to calculate volume of cylinders, cones, and spheres as well as calculate missing dimensions for real-world problems. Students will use these skills to determine the difference in volume of a rectangular shaped pool and a cylindrical shaped pool. Also, student will look at the amount of space four ice cubes take up after melting into a cylindrical shaped container. The ability to use and explain volume formulas is a major work for Level E Geometry.

Students will use many previously learned skills in this lesson in order to calculate volume and the missing dimensions when given volume. Students will need to have an understanding of substitution and solving equations for a variable. Students will also need to be familiar with converting units of measure.

## Wrap it Up - Part 1

The purpose of this lesson is to expand student knowledge of using the surface area formulas. Students will use surface area formulas to calculate the surface area of rectangular and right prims, and pyramids as well as calculate missing dimensions. The ability to determine the surface area and use and explain formulas is a major work of Level D Geometry.

Students will use many previously learned skills in this lesson in order to calculate surface area and the missing dimensions when given the surface area. Students will need to have an understanding of substitution and solving equations for a variable. Students will also need to be familiar with converting units of measure.

## Divide and Conquer

The purpose of this lesson is to further student knowledge and experience with formulas. The students will use the knowledge from the previous lessons in this unit to work problems involving composite figures. This lesson will involve problems requiring various formulas to solve for volume and surface area of composite figures.

Students will use many previously learned skills in this lesson in order to calculate surface area and the missing dimensions when given the surface area or volume. Students will need to have an understanding of substitution and solving equations for a variable. Students will also need to be familiar with converting units of measure.
