Geometry: Degrees of a Circle

While working with our Waldorf curriculum from
http://www.live-education.com
we decided to do the project on “Angles and Degrees” three different ways. We’ll do this project with watercolors, watercolor pencils and color pencils.

We will divide the circle into acute angles, a right angle and an obtuse angle. We will color in each section with a different color, then mark the angle.

he first project uses watercolors, embossing powder and an embossing pen. This method involves special tools and materials that can be found at local craft stores or from
http://www.dickblick.com

Materials for this project: watercolor paper (or drawing paper), watercolors (we used Distress Inks), embossing pen, embossing powder, and heat tool. You can also do this project with watercolor pencils or color pencils.

Tools needed: protractor, compass and a ruler.

  1. We are currently working on a geometry unit, so we attempted your ‘triangles from intersecting lines’ video. The kids really enjoyed it and they turned out great!!! Thanks. We have also been incorporating Islamic art & design (Islamic geometric shapes) into our unit. In case you are not familiar with the following books, I highly recommend checking them out. They are a great addition to this unit…they add a bit of Islam, history, art & math altogether 🙂

    1. Thanks for sharing the books! I immediately plan to purchase the Genius of Islam. I was only familiar with the Islamic geometric design book which a friend lent me recently and found it fascinating. It seems like the same steps needed to construct complex geometric designs today in computer programs are the same as in the past. Amazing! I’m so happy for your success in making your triangles from intersecting lines. I would love to see pics via Facebook.
