Partners Activity for graphing Parametric Equations. Print out a class set of the 16 x(t) equation cards and the 16 y(t) equation cards. Each partner pair gets an x(t) equation card and a y(t) equation card.The first two pages are for the students to record their and their partner's x(t) and y(t) equations. Then they must work together to record the t,x(t), y(t) table and graph their parametric. They then swap cards with neighboring partners until they have all 6 problems completed. The x(t) and y(t) functions include basic linear, square, square root, rational, and absolute value functions.
