This highly engaging task encourages students to use mathematical modeling to predict how many pennies it will take to cover a large circle. Students begin by using simpler problems (i.e., smaller circles) to generalize using a linear, quadratic, or exponential function.

Mathematically:

*Requires students to confront the question of whether a model's predictions are reasonable (part of the modeling cycle)

*Sets up a situation with many avenues for mathematical investigation

*Uses technology efficiently to support the mathematics

In the classroom:

*Allows for student collaboration and discussion

*Provides a platform for the teacher to view students' work online

*Allows teacher to filter results, e.g., to see which students revised their models
