I am a NYC Teaching Fellow at one of the last remaining large high schools in the Bronx. We have nearly 5000 students in a building designed for a much smaller population. My classes have as many as 34 students. In this crowded situation, technological resources are scarce.
The National Council of Teachers of Mathematics (NCTM) standards, which forms the basis of NY state and city guidelines, encourages the integration of technology into the mathematics classroom. One very flexible means to do this is with a graphing calculator that has programming capabilities built in. Direct instruction (sometimes called "chalk and talk") doesn't hold the attention of the students; graphing calculators not only hold their attention, but they help them to see mathematical connections in ways that allow them to gain true insight and understanding into mathematical relationships.
The TI-83 family of calculators is the standard approved for use on the Regents examinations, but for those trying to continue to college and those taking advanced math classes, the TI-89 is strongly recommended. Unfortunately, students who cannot even afford lunch cannot be expected to buy their own calculators. I would like to have a class set of thirty-five TI-89 calculators to let my students use during my pre-calculus class. This proposal is for fifteen of the desired thirty-five (I'm creating two other identical proposals).
Graphing calculator technology truly empowers and motivates my students. It is difficult to elicit excitement about math, but I've seen graphing calculators reinvigorate the students' learning
