- It is fine if two students in the group choose the same pyramid.
- Next, the students need to draw a net for their pyramid. Have them include measurements of each part of the
pyramid. - Then, students need to find the surface area of the pyramid.
- The lateral area of the pyramid
- The volume of the pyramid
- Have students show all of their work.
- When finished, they need to check the work of one other student in their group.
- Finally, collect student work to assess levels of understanding.
- Intelligences- linguistic, logical- mathematical, visual- spatial, interpersonal, intrapersonal.
III.SpecialNeeds/Modification
- Define regular pyramid.
- Identify types of pyramids according to each base.
- Define slant height.
- Write the formulas for surface area, lateral area and volume on the board.
- Be sure students understand how to find each measurement.
IV.AlternativeAssessment
- Collect and review student work.
- Is the net correctly drawn and labeled?
- Is the surface area of each net correct?
- Is the lateral area of each correct?
- Is the volume correct?
- Have there been any corrections to the work of the students by a peer?
Cones
I.SectionObjectives
- Find the surface area of a cone using a net or formula.
- Find the volume of a cone.
II.MultipleIntelligences
- Begin by having the students work to build cones.
- Students begin by drawing a half circle and measure the top of it.
- This top measurement becomes the circumference of the cone.
- Then they cut out the half circle.
- Have the students turn it into a cone.
- Then use the descriptions of the parts of the cone in the text to help the students to understand the parts of the
cone. - After this teach the material in the lesson and then move on to the next activity.
- Next, divide the students into groups.
- In each group, ask the students to choose either the surface area formula or the volume formula.
- With each formula, the students need to find a way to teach how the formula is put together for the other
students in the class.
