cctm- TI applications

presented by TI rep wgarciano@ti.com, more info at TI's educational website.

  • Demoed some of the applications on the TI-84 plus silver addition.
  • There is an application to graph inequalities and within that application is a way to graph a vertical line, i.e. X = 3. The other calculators only graphed functions of Y. This X= screen is only available with the inequality graph.
  • There are pdfs on the sites of each application that describe the nuts and bolts for students to use it.
  • The transformation graphs application looked very useful since that is a hard concept for our students to understand. This application allowed the parent function to be graphed and the constants manipulated manually, or run through an animation that showed dynamically the affects of some of those constants in transformations.
  • Looks worth spending some time on students after the initial concept is taught. These calculators are allowed on standardized test such as ACT, AP and IB tests so hopefully this can help.

I am interested to see if these tools help. Maybe some action research within the department so see if they get a better or worse grasp on the concepts and how it helps with problems solving and/or test taking? Anyone interested?

In addition, there is a free TI-Nspire workshop at :
