**Making “Sense” of Functions**

Student comprehension of functions is more complete when they are presented with multiple representations. In this session, participants will examine functions outside of the traditional numerical, algebraic, and graphical models. Using the TI-Innovator, numerical input will be transformed into real world output that students can see and hear. Real world input will then be used to create numerical and graphical output.

**In Search of a Model: Collecting and Analyzing Data with TI Technology**

In a data-driven world, students must be able to choose appropriate models to make reasonable predictions. In this session, participants will use various TI-Technologies to collect multiple sets of data. An analysis of each set will be performed with the results interpreted in context of the sample collected. The appropriate model for each will be discussed as the meaning of the coefficient of determination, R ^{2}, is explored.
