“Justifying and explaining ideas improves students reasoning skills and their conceptual understanding.”

(Maher and Martino)

1. Using a scale - Rate each problem in comparison with each other. - Record under Rating #1.

2. Working with a partner - directly model each problem, discuss the difficulty if the problem is directly modeled

3. At your table, discuss a mutual ranking. Think about the rationale - Rating #2.

Watch Rachel solve the problems.

How difficult of a problem is it for Rachel?

Does Rachel have a plan?

Does Rachel know how to solve the problem?
