Using the TI-73: A Guide for Teachers
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.
