Lesson Plan: Rotations on the Coordinate Plane Mathematics • 8th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the vertices of a shape after it undergoes a rotation of 90, 180, or 270 degrees about the origin clockwise and counterclockwise.
Objectives
Students will be able to
- understand the transformations on the coordinates of a point when it is rotated about the origin on the coordinate plane by counterclockwise,
- identify equivalent rotations on the coordinate plane,
- identify the image of a point, line segment, or shape after a given rotation about the origin,
- rotate points, line segments, and shapes about the origin by multiples of ,
- understand the properties of rotation about a point.
Prerequisites
Students should already be familiar with
- rotating points, line segments, and shapes about points not on the coordinate plane,
- positive and negative angles of rotation referring to counterclockwise and clockwise rotations respectively.
Exclusions
Students will not cover
- rotations about the origin that are not a multiple of ,
- rotations on the coordinate plane that are not about the origin.
