Is It a Function? Game

The object of this lesson is to allow students to recognize functions and give their equations.

RULES:

Students are divided into groups of 4 and then 2 groups of 2.

1. Group 1 makes up a rule for f(x).

2. Group 2 gives values of x, one at a time.

3. Group 1 answers with the value of f(x) by substituting into their rule.

4. Group 2 keeps a record of the values in a table.

5. Continue steps 2 - 4 until group 2 can guess the rule.

6. Decide as a team whether the rule constitutes a function.

7. Reverse roles and try again.
