I am looking for advice from teachers who are experienced with TI Nspire. I have been doing some webinars through TI on this type of calculator.
We currently use TI-84's with the new OS in our school, and I was considering doing some grant writing with the goal of getting a class set of Nspires. Before I do that, I wanted to hear some of your experiences about how much the the Nspires help compared to TI-84's. (I primarily teach Algebra 2 and Trig.)
