2. Agenda
Introductions
Creating a Cheat Sheet: TI-Nspire CX keys and functions (15 min)
Regular and Irregular Computational Tasks (15 min)
Share Out: Aha! Hmmm… Huh? (10 min)
“Say It with a Survey” Activity (20 min)
Resources (10 min)
Reflections and Follow-Up (5 min)
This hands-on session will feature a variety of middle grades activities using the TI-Nspire handheld.  The TI-Nspire is capable of computations with fractions and has a wide array of available representations including circle graphs, bar graphs, dot plots, histograms, and box and whisker plots.  Much more than just a graphing calculator.  TI-Nspire handhelds will be available for use.
