Mr. Bentz is fortunate to have students who are taking Calculus 2 in high school. Because of this, he was able to get seven TI-NSpire calculators. Along with this, he has the software which can be implemented with the SMARTboard.
View how Mr. Bentz talks about how the SMARTboard allows for students to interact with the EXACT tool that students can use on the AP exam. While I have the iPad version of the TI-NSpire, the app IS NOT allowed on the AP test.
