On a nice day just a week before school let out for the summer, nine pre-calculus students took to the street to draw a giant Unit Circle in chalk as a part of their trigonometry unit. The students included, left to right: Troy Tellinghuisen, Jayden Cullen, Ben Sullivan, Hannah Honrud, Kayla Hodgen, Analea Erickson, Montana Osterman, Alyssa Studer and Dan Ingebrand.

The class was still hard at work even as the school year neared its end, learning about special triangles and angle properties as a part of their trigonometry unit.


Outside of the school, kids drew a giant unit circle (a standard piece of knowledge in mathematics) in chalk on the street, and then answered questions off of it.
