Using the TI-73: A Guide for Teachers

Patterns

12. Tell students:

Digging deeper, the Rover found evidence of other communities that had different numbers of antennas.

13.Have your students repeat the above activity using other numbers of antennas per Martian. See if they can write a rule for each.

Have them enter their rules in the Y= editor (&) and use the table as before.

Wrap-up

Have students draw their Martians with a different number of antennas and show how they adapt to their environment. Have them include a description and the rule for each.

Extensions

Write problems telling other adaptations the Martians may have needed, such as more arms, toes, eyes, etc.

Find the rules for each of their problems and explore on the table for different community sizes.
