In this activity students will sort cards into two categories: "Functions" or "Not Functions". There are a total of 30 cards (15 cards that represent functions and 15 that are not functions). Each card has either an input/output table or a graph on it so students must know how to recognize a function from either a table or a graph. Included in the bundle are printable cards for students to use in pairs or small groups, printable headings to sort the cards and an answer key.
(It is suggested that you print and laminate a set of cards for each pair of students.)
