EDC and Texas Instruments have enjoyed a close working relationship for nearly 20 years. Both TI's new line of handhelds, the TI-Nspire, and EDC's forthcoming curriculum, CME Project, have evolved from this relationship.

This presentation looks at how curriculum and classroom needs drove the new interface, and how the new interface influenced the timing and development of certain key topics. Among other things, the talk looks at field–tested approaches to using CAS to:

• define and manipulate functions
• explore the slope of a curve at a particular point
• factor, expand, and manipulate polynomials
