Geometry, Teacher\'s Edition

(Axel Boer) #1

  • 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.
