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.  Come hear the difference between linear and exponential functions.

 Design and Production: Investigating the Effects of Error with CAS

Mathematics in the “real world” can be frustrating. Small variations in input values can lead to large variations in results. While the mathematics for the relationship between these variations can be daunting for students, technology
can make these problems accessible. In this session we will have a design task and discuss possible errors that may arise in its production. We will use CAS and dynamic geometry to explore how these errors affect our final product.
