This is the second part of a try-it-and-change-it exploration of angles. It contains some scripts to experiment with. Suggestions are in comments "inside" the project. 1. Try them. 2. Then try the puzzles. 3. Then make them do new things, experimenting and using your own ideas.
This is not a "project" but a small set of experiments with angle, built around the Massachusetts framework for fourth grade, as one part of an introduction to thinking about angles and angle sizes. The model curriculum unit (MCU) that this accompanies is part of an ongoing effort of the Massachusetts Department of Elementary and Secondary Education. This particular Scratch experiment, and the MCU that it is part of, was designed at EDC with NSF support.
