Sketchy Dilations

In this lesson, students are informally introduced to dilations through experimenting with "sketching machines" that allow them to adjust various parts of a drawing to see the effect on the pre-image. Students are then introduced to similarity as the result of a dilation. Inspired by and with gratitude to Illustrative Mathematics and OpenUp Resources.
