Students might notice in this visual:
- There are two columns labeled input and output.
- The numbers in the input column increase by the same amount.
- There’s a pattern between input and output numbers.
- The output numbers follow a consistent pattern.
- The rule tells how the input changes to become the output.
EXTENDING THE DISCUSSION
After the observational question, randomly call on one or more students to share what they or their partner answered. Then ask the class, “Did anyone notice…?” using the suggestions above or anything else you’ve noticed.

Students might wonder:
- How do I figure out the rule for the input/output table?
- Can the rule be multiplication or subtraction instead of addition?
- What would happen if the rule changed?
- Could there be more than one rule that works?
- Why do we use input/output tables in math?
EXTENDING THE DISCUSSION
After students have shared what they notice, ask the class, “Did anyone wonder…?” using the suggestions above or anything else you might think is interesting or relevant to the lesson.
