Teacher Felicia Taylor Geometry Honors 8th 29 8: Three-Dimensional Measurement
Standard(s) Taught

#### Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).

Learning Targets and Learning Criteria

I can…

• Volumes:
• identify the base for prisms, cylinders, pyramids, and cones.
• calculate the area of the base (B) for prisms, cylinders, pyramids, and cones.
• calculate the volume of a prism using the formula V = Bh and the volume of a cylinder V = πr2h, where B is the area of the base and h is height of the solid.
• defend the statement, “The formula for the volume of a cylinder (or cone) is basically the same as the formula for the volume of a prism (or pyramid).”
• explain that the volume of a pyramid (or cone) is 1/3 the volume of a prism (or cylinder) with the same base area and height.
(Demonstrate rule for students, for example with liquids or bird seed.)
• use Cavalieri’s Principle to demonstrate that a right prism (or cylinder) and a slanted prism (or cylinder) have the same volume when the base areas and heights are the same.
• calculate the volume of a cylinder, pyramid, cone, and sphere and use the volume formulas to solve problems.
• find the volume when one or more dimensions are changed.
• describe real world objects using geometric figures.
• use measures of geometric shapes to find volume, surface area and lateral area of real-world objects.
• apply the properties of geometric figures to solve real-world problems.
•  decompose a figure in smaller parts to describe the properties of the object.
