# Lesson Plan: Points, Lines, and Planes in Space Mathematics • 11th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify and model geometric concepts like points, lines, and planes in space along with their properties.

#### Objectives

Students will be able to

- describe the possible configurations for two lines in space: parallel, intersecting, or neither (i.e., skew),
- understand and visualize how three noncollinear points or two intersecting lines define a plane,
- describe the possible configurations of a line and a plane: a line and a plane intersecting at a point, a line included in the plane, a line parallel to the plane but not included (thus not intersecting),
- identify the intersection between a plane and a line or between two or three planes.

#### Prerequisites

Students should already be familiar with

- lines,
- 2D and 3D shapes.

#### Exclusions

Students will not cover

- coordinates of a point,
- equations of lines and planes.
