Lesson Plan: Dilation: Negative Scale Factors Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to dilate shapes about a center of dilation by negative scale factors, fractional numbers, and whole numbers and describe dilations.
Objectives
Students will be able to
- dilate a shape about a center of dilation by a negative scale factor (integer or fraction),
- determine the center of dilation and its scale factor given a shape and its image by the dilation.
Prerequisites
Students should already be familiar with
- dilations by positive scale factors.
Exclusions
Students will not cover
- combination of transformations.
