This rich task is designed to be a follow up to the previous task about finding a formula for a physical pattern. This task, however, can be used to deepen understanding of that process of building a function or this task can be used to assess learners' understanding of that process--or both. This rich task is will require use of the Common Core Mathematical Practices. The use of manipulatives is recommended, but not required.
