New Year's Eve's Times Square Ball - It's a gorgeous ball, covered with Waterford Crystal triangles, shaped as a geodesic icosahedron. Every New Year's Eve it descends in Times Square to mark the beginning of the new year. Students take a closer look at this construction and use our drawings to experiment with slicing an icosahedron in order to discover how this shape is formed.

*Games are great during the break.*

Where should I drop my puck - (3-act activity) Students study our penguin peg board and decide which slot has the greatest potential to score big points? They also find the number of paths from each top slot.

Games with dice - Students calculate the probability of different sums when rolling dice. They look at how the theoretical outcomes compare with the experimental tallies of their dice throws and consider how the sample size affects the closeness of these two probabilities.
