# 5.6: Follow the Rule

**Follow The Rule - Complete one-step function tables**

In these problems, students follow rules presented in words and with symbols to complete two-column function tables. Each of the rules requires one computational step. For some rows in the tables, students have to apply inverse operations to figure out the value of the variable. Problems 1-6 use addition or subtraction. Problems 7-12 use multiplication or division.
