Missing Figure, Factor, or Copy

This Instructional Activity is a part of the Lesson 5, Unit 1, Grade 7. In this activity, students investigate different aspects of the figure, scaled copy, and scale factor trio. Given any two of these three, we can find the third. Students work with these different scenarios on a grid, dealing with scale factors greater than 1, less than 1, and equal to 1. In addition, they create a scaled copy of a non-polygonal figure off of a grid. Both on and off of a grid, students need to decide what tools to use in order to measure angles and side lengths in order to produce the scaled copies.
