Discuss possible growth patterns for other double worms. Have student pairs select a double worm from the following list:

• Two-Eyed Double Worm that has 2 squares at birth
• Four-Eyed Double Worm that has 4 squares at birth
• Six-Eyed Double Worm that has 6 squares at birth

Students should include the following information in their problems:

• Draw a picture showing how many squares their creature has at birth.
• Draw a picture showing how many squares it has after a year.
• Draw a picture showing how many squares it has after two years.
• Create a data table showing growth up to 5 years.
• Write 1–2 questions about the growth of the double worm.

Upon completion, have student pairs present their drawings and ask the class to solve the problems about their double worm.
