Pages 1-4 are 32 cards with functions (rational, polynomial, and piecewise). Pages 5-8 are posters to post in the corners of your classroom (infinite discontinuity, jump discontinuity, point discontinuity, and continuous). Each student gets a card and must go to the correct corner of the room, based upon which type of discontinuity (if any) is present in their function. You can check their answers with the key. They can shuffle cards and repeat as many times as you like.
