# 7.8: Two-Step Patterns

**Two Step Patterns – Identify Patterns and Write Function Rules**

**Teacher Notes**

Two Step Patterns require students to analyze the first 3 or 4 figures of a pattern, identify relationships between the pattern number and the number of items needed to draw the figure, describe the figure, and write the rule (in symbols) that relates the pattern number and the number of items. All rules require two steps: multiplication and either addition or subtraction. Encourage students to make a table to organize their data. The table will help them to observe the relationship and write the rule.
