This is a great review game for linear and nonlinear functions in eighth grade math. It includes 15 essential vocabulary words and formulas in an "I Have Who Has" game. My station rotations are in groups of four. I like to use this as a group station. Just laminate and cut out the cards. Be sure that all of them are distributed to the students in the group. One student begins by reading the "Who has...." question from their card. The student with the correct response then reads their whole card. The game is over when all cards have been read. I laminate the included student directions to keep at the station.
This activity would be great to review before a standardized test or classroom test.

Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.1
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
