Unit Circle Projects

After years of seeing other teachers share pictures of the unit circle projects their students created, I decided to finally take the plunge.  I assigned my trig students the task of creating a visual representation (2d or 3d) of the unit circle in lieu of a semester test in trigonometry.

A nice side effect of this projects is that now I have a lot more student work decorating my classroom!  I teach mostly Algebra 1, so it’s been fun to see these students notice the projects and start to ask questions about what a unit circle is!

Looking through the projects, the biggest problem my students are having is wanting to space all of the angles evenly.  Though, the fact that they most likely don’t have protractors at home is probably the main culprit!

Here’s what they came up with!  (Be sure to scroll to the bottom to see how one student combined his passions for welding and trigonometry!)

This is the unit circle project that has generated the most conversation amongst my students from other classes.

Do you have the instructions you gave the students available for us to see?

I just checked my school files for that year, and I unfortunately cannot find the instructions I handed out. Sorry!

I would love to see them too. I would like to do this after winter break as we co e back for a week left. Did you give them any in class time to work on this? If so, what did the student who welded his project do? Thank you for all you share!!!
