My support classes are about to take their test/quiz on all conic sections in their Math 3 classes. I let my classes divide themselves into groups of 3 and then they had to get a large sheet of paper and 1 parabola question from me. They completed a total of 3 problems where their where either given the equation of a parabola and answered questions and graphed or the graph of a parabola where they answered questions and wrote the equation of the parabola.
1) Happy with the overall result and it helped that in order to get the next problem, they had to have everything correct on the current problem.
2) Will have students work in groups of 2 next time. I feel it makes each student more accountable for more of the work.
For an overall review, I am using the model but with 4 problems addressing parabolas, circles, hyperbolas, and ellipses.

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
