(2) Students will deepen their understanding of solid gures through observation, manipulation and experimentation. Moreover, students will further their ability to measure geometric gures.
a. To become aware of spatial relationships among lines and planes in space.
b. To perceive solid gures as being composed of motions of plane gures along a line or a
plane; to represent solid gures on a plane; and to identify properties of solid gures from
their representations in a plane.
c. To be able to calculate the arc length of a sector and its area; to be able to calculate the
surface area and the volume of pyramids and spheres.
