Meece Middle School
Mrs. Robin Crawford
Unit 5: Similarity and Transformations
Class: Accelerated Math
Grade: 7 Days in Unit: 13
Objective:
Solve problems involving similar figures.
Apply proportionality to measurement, including scale drawings and constant speeds.
Determine how changes in dimensions affect the perimeter and area of similar geometric figures, and apply these
relationships to solve problems.
Predict the results of transformations and draw transformed figures, with and without the coordinate plane.
