When I was first introduced to a CAS device, I thought it was a great tool for my AP Calculus class. The more I used CAS activities I realized it would be a great tool for all math. I believe student investigations are key in deeper understanding of mathematics. CAS devices such as the TI-Nspire CX handheld and iPad app give students the opportunity to investigate the why’s and how’s of math. If I write the steps on the board, the students only half believe. If I give them technology and pose a “dilemma” such as why does ½ + ⅓ = ⅚, then the real learning begins. I created this blog to share my experiences with and thoughts about using CAS in all grade levels.

I was an engineer for 6 years before I became a teacher. I've taught math 6th - 12th grade, computer science, and EAST (Environmental and Spatial Technologies). I also provide professional development in the areas of technology and STEM learning. I have been providing professional development since 2007 locally and nationally. I created an Engineering Club at my current high school for students interested in STEM fields and am proud to be the 2011 Student Racing Challenge National Champs. My two personal passions are NASCAR and travelling. View all posts by Michelle Bonds
