**Transforming Roots and Asymptotes**

Explore the behavior of polynomial and rational functions with dynamic learning tasks that make use of technology. A deeper understanding of the graphs of both families of functions will be developed by activities designed to help students discover relationships between algebraic and graphical representations.

**Fair and Consistent Grading of Student Work (with Marshall Ransom)**

We focus on grading student work in a fair and consistent manner, rewarding correct mathematics. Example problems and student work will be discussed including percent, basic algebra and basic geometry. Teachers will be asked to work through the grading process and then to prepare a fair and consistent grading standard for a problem.

**Moving Towards Understanding with TI-Rover**

Student understanding of mathematics is more authentic when it is presented with multiple representations. Participants will examine mathematical ideas of the traditional numerical, algebraic, and graphical models in the context of the real world. Using the TI-Innovator and TI- Rover, numerical input will be transformed into real world output that students can experience. Output from the Innovator and Rover will help students make sense of algebraic and geometric problems as they persevere in solving them.
