In this activity students will sort cards into two categories: "Linear" or "Nonlinear". There are a total of 42 cards (21 cards that represent linear functions and 21 that are not linear functions). Each card has an equation, a table of values, a graph or a verbal situation on it. 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.)
