- Then they will draw a net of the cylinder.
- Finally, they can cut the net out and build the actual cylinder.
- When finished, each group should have two cylinders constructed.
- Allow time for the students to share their work.
III.MeetingObjectives
- Students will find the surface area of cylinders.
- Students will find the volume of cylinders.
- Students will use their work in problem solving.
IV.NotesonAssessment
- Check student work for accuracy.
- Are the cylinders in proportion?
- Did the students calculate the surface area correctly?
- Did the students calculate the volume correctly?
- Did the students construct the second cylinder?
- Listen for student understanding of surface area and volume during student presentations.
Pyramids
I.SectionObjectives
- Identify pyramids.
- Find the surface area of a pyramid using a net or formula.
- Find the volume of a pyramid.
II.ProblemSolvingActivity-CreateYourOwnPyramid
- For this activity, the students are going to design their own pyramids.
- First, they need to decide which polygon to use as a base.
- The project has two parts to be completed- the first is a diagram of the pyramid done with a scale, the second
is an actual model of the pyramid. - Students need to decide how large they want their pyramid.
- They can use these measurements to design the actual pyramid.
- Once they know how large they want to actually build a pyramid, they can draw a design to show their work.
- After the design has been completed, the students must figure out the surface area and the volume of the
pyramid. - The final stage is to draw a net (in actual size) and cut it out to construct the pyramid.
- Allow students time to share their work.
- Some students will build large pyramids, others small- either is fine as long as the work is accurate.
III.MeetingObjectives
- Students will identify pyramids.
- Students will find the surface area of a pyramid using a net or formula.
- Students will find the volume of a pyramid.
- Students will demonstrate their understanding through a design and a model.
