Think about Sara's work and reflect on the following questions:

What conjecture is the student able to make on her own?
How does the student justify this conjecture?
What is the limitation of the student's conjecture?
How does the teacher help the student find a general pattern for any number of rods? Can you think of another approach?
What question might you ask to help the student clarify her explanation in the last question?
