**How Many Ghosts Do You See?**

This activity encourages students to apply the patterns in Pascal's Triangle. A teacher instructional plan with mathematical background, answer and challenge is included to explain how to present this problem, which is also an outgrowth of the Rutgers Discrete Math Institute.

A recording sheet is also included as part of the teacher packet so that students are able to record all different solutions using a

**systematic counting**method, which is a goal of discrete mathematics.
