- Then you will need to figure out the surface area of each of the boxes.
- Write each surface area on an index card.
- You will need as many boxes as you have students in one class.
- Then you bring all of the boxes to the classroom.
- To complete the activity, each of the students is given a ruler/tape measure and an index card with a surface
area on it. - Students will need to take notes as they work- remind them to do this.
- Also encourage students to think of strategies before beginning the task.
- Does a large box have a large surface area or a small surface area?
- Then the students need to figure out which box has their correct surface area.
- This will take some time.
- Don’t rush the students, but encourage them to work together.
- Once they have found their box, the students need to create a diagram of it.
- Label the surface area and find the volume of the prism.
- Allow time for the students to share their work when finished.
III.MeetingObjectives
- Students will find the surface area of a prism.
- Students will find the volume of a prism.
- Students will show their work in a diagram.
IV.NotesonAssessment
- Did the students match up the correct prism with their measurements?
- Is the diagram labeled accurately?
- Is the volume of the prism correct?
- Offer correction/feedback when necessary.
Cylinders
I.SectionObjectives
- Find the surface area of cylinders.
- Find the volume of cylinders.
- Find the volume of composite three- dimensional figures.
II.ProblemSolvingActivity-CylinderSizing
- For this activity, the students are going to need a variety of different size cylinders to work with.
- This activity is going to combine our work with cylinders and scale factor together.
- Students can work in groups.
- Each group selects a cylinder to work with.
- First, the students need to figure out the surface area and volume of that cylinder.
- Next, the students are going to create a cylinder that is three times as large as the one that they have in their
hands. - Students will need large pieces of paper, scissors, rulers, string, tape or glue.
- The students will have to figure out the dimensions of the new cylinder.
- They will need to figure the surface area and the volume of the new cylinder as well.
