Resumen de Second differences: a mathematical bridge between two projects.

Joyce Fischer, S. G. Wayment, Christopher Johnson

• Making connections is one of the most important foundations involved in learning mathematics. Two projects are presented in this article: one involving Newton's Second Law of Motion and the other involving the determination of star numbers, a type of figurate number. The two invoke seemingly different modalities for students at different levels of mathematical maturity, and yet they share a deep academic connection.
