What students learn

In this lesson, students draw, construct, and describe geometrical figures and describe the relationships between them.

Students also solve real-life and mathematical problems involving angle measure, area, surface area, and volume.

  • Solve problems involving scale drawings of geometric figures. Draw geometric shapes with given conditions.

  • Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids. Use the formulas for the area and circumference of a circle to solve problems.

  • Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

  • Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
