Understand and explain how scale factors of 1, less than 1, and greater than 1 affect the size of scaled copies. Let's look at the effects of different scale factors. Learning targets: students can describe the effect on a scaled copy when students use a scale factor that is greater than 1, less than 1, or equal to 1. They can explain how the scale factor that takes Figure A to its copy Figure B is related to the scale factor that takes Figure B to Figure A.
