This set of cards can be used to review both the chain rule and implicit differentiation in Calculus or Calculus AP. Each card has a problem displayed in the center of the card and an answer to another problem, in a magnifying glass, at the bottom right of the card. If you use the 10 cards with a red heart you will have a scavenger hunt with 10 cards. These 10 cards focus on the chain rule. If you use the 10 cards with a blue diamond you will have a scavenger hunt that focus on Implicit Differentiation. The 20 cards with a black club form a combined set.
