# Prepare a Presentation

- Describe each method you used to solve the marble problem.
- Think about the words—particularly the mathematical vocabulary—you used to describe each method. What do the words mean? Are there any words that you used to describe one method but not the other two?
- Be prepared to share your description of each method with the class.
