The teacher will use the CBL 2 and attached probes to generate sinusoidal data. Using TI-Navigator, the teacher will send the data to the students, and the students will try to find a sine curve to model the given data.

This activity will allow the students to determine the domain and range of many different graphs presented to them through TI-Navigator using the activity center.

In this activity students will contribute a set of random points to a graph of a circle of radius 1 inscribed in a square. They will estimate the area of the circle using geometric probability.
