Being that my husband in a math teacher I am always on the lookout to incorporate math in an artistic way. Frank Stella's protractor series does just that. I had the students look at his paintings and asked how he placed the protractor on his paintings. Some answers I received was that protractors appeared:
-right side up
-place next to or below another protractor
The list is really endless. I gave each student a protractor (purchased from my own pocket) and had them trace in 4 or 5 times. To create a better colored pattern students were told to only use 4 or 5 colors and the shapes were colored in using markers. The kids love markers, as do I for the easy clean up. The result are these beautiful abstract drawings. These are 2 works in progress I will post a finished product soon.
