- The students will demonstrate the meaning of each part of the formula and present an example of how to use
the formula. - Intelligences- linguistic, logical- mathematical, visual- spatial, bodily- kinesthetic, interpersonal, intraper-
sonal.
III.SpecialNeeds/Modifications
- Define cone as a single curved base that tapers to a single point. This point is called theapex.
- Base can be a circle or an oval.
- Right cone- apex in the center
- Oblique cone- apex not in the center
- Write the formulas for surface area and volume on the board.
IV.AlternativeAssessment
- Create a checklist of the things that the students should be teaching in their lessons.
- Use these checklists during the presentations.
- Make notes of the things that the students cover.
- Be sure to provide feedback for the things that the students miss in their presentations.
Spheres
I.SectionObjectives
- Find the surface area of a sphere.
- Find the volume of a sphere.
II.MultipleIntelligences
- Begin by showing students some spheres of different sizes. You can use a baseball, a globe and a basketball
for example. - Often the measurement of a ball is given according to the diameter. Have the diameter of any object that you
show the students close by. Use one- for example, a fourteen inch basketball to demonstrate the following. - Parts of a circle
- 1.O=center point
- 2.r=radius (^12 of diameter)
- 3.d=diameter
- Chord- intersects the center of the circle or sphere.
- Secant- line, ray or line segment that intersects in two places and extends OUTSIDE the sphere
- Tangent- intersects the sphere at only one point.
- SA of a Sphere- use the formula and then use the examples to have students work to find the SA of one or
more of the given objects. - For example, find the SA of the 14” basketball.
- Volume of a sphere- use the formula and then use the examples to have students work to find the volume of
each given object. - Allow time for students to share their work.
- Intelligences- linguistic, logical- mathematical, visual- spatial, bodily- kinesthetic, interpersonal, intraper-
sonal.
