My juniors have started their venture into conics. In my support class, we have started to cover circles. I wanted a quick, decorative activity that would take less than 15 minutes but would still have my students solving problems.
I allowed my students to either work by themselves or with one other person. Each grouping got a plate and had to label/find the following on it:
1) Label the radius and center of the paper plates
2) Find the radius and center of the circle described by the equation: _________________
3) Write the equation of the circle with a center of _____ and radius of _____
4) Create an equation for a circle and identify the center and radius of it
I had each group tack their finished plate to my board and my class votes on the prettiest one--that group received a 120 on the assignment
