- Find the surface area of cylinders.
- Find the volume of cylinders.
- Find the volume of composite three- dimensional figures.
II.MultipleIntelligences
- To differentiate this lesson, you can make it very hands- on by using some different cylinders. Example-
Quaker Oats containers, soda cans, etc. - Teach the material in the lesson.
- Then have the students work to find the surface area and volume of each cylinder.
- The students will need string to determine circumference, rulers, colored pencils and paper.
- Have students draw a net for their cylinder and label all of the measurements involved.
- Then they complete their work.
- Provide time for students to share their work in small groups.
III.SpecialNeeds/Modifications
- Review finding the area and circumference of a circle.
- Define cylinders.
- Show students the difference between right cylinders and oblique cylinders.
- Write out the formulas for surface area and volume of cylinders.
- Steps to Working with Composite Solids
- Break each composite solid into its smaller solid parts.
- Select the correct formula for either surface area or volume based on the problem.
- Find the surface area or volume of each smaller solid.
- Add/subtract the results of the surface area or volume based on the question.
IV.AlternativeAssessment
- Observe students as they work in small groups.
- Have the students share their work from the cylinder activity when finished.
- Check student work for accuracy.
- Provide assistance and feedback when necessary.
Pyramids
I.SectionObjectives
- Identify pyramids.
- Find the surface area of a pyramid using a net or formula.
- Find the volume of a pyramid.
II.MultipleIntelligences
- Differentiate this lesson by having students complete the following activities.
- Students are going to be working with a pyramid of their choosing.
- Begin by dividing students into groups. While the students will be working with different pyramids, they will
have the support of the other students in the group as they work. - Each student is to choose a type of pyramid: triangular, square, pentagonal, hexagonal, etc.
