This is a matching activity. There are 32 cards... 8 equation cards, 8 verbal description (linear, quadratic, absolute value, not a function) cards, 8 graphs, and 8 tables. The objective is to get eight four-way matches.
I usually do this task cooperatively in randomized pairs in the first quarter of my algebra one class. I do not allow technology of any kind for this activity, though the students do need paper and pencil for plotting points and evaluating.
Copy as many of the cards as you need onto colored paper (use heavy stock and laminate your cards if you want to use them each year). Note: You can double-side them with the FUN WITH FUNCTIONS! on the back like a real card game, but this is optional. Cut them out and put them in zip-lock bags, one set per bag. Each pair gets one bag of cards, and one empty grid on which to record their answers.
The answer key is included. My students love this activity because they get to work in pairs. I love this activity because they sound so smart as they are talking and trying to figure it out!
