Revised Calculator Use Policy
(found on pages 21-22 of the student handbook)

The Mathematics Department believes that technology is an important tool that enhances student learning. The TI-84+ graphing calculator is required in all courses, beginning with Algebra I. These calculators are allowed for the ACT and Prairie State tests junior year, the SAT, Advanced Placement tests, and are allowed at most universities. (The models called “Silver” have much more memory and some extra features. They are a bit more expensive and are not required, although they can be used.)

Students who purchase other brands or models risk being at a disadvantage in the classroom setting. Students will not be required to purchase another type of calculator.

With the ability to link calculators to a computer and update them via the Internet as new features and operating systems become available, students should rest assured that the calculator will be adequate for their entire high school career.

The use of the calculator for an individual course is at the discretion of the teacher. While a calculator is an invaluable tool for studying mathematics, there will be times when the instructor deems that a particular topic or skill is more appropriately investigated and assessed without the use of a calculator.

Students are expected to demonstrate the utmost personal integrity in using the calculator. Inappropriate uses of the calculator include, but are not limited to:
  • Playing calculator games during class
  • Storing formulas, notes, programs, and/or answers unauthorized by the teacher
  • Sharing a calculator during a quiz, test, or final exam
  • Using the calculator on an assessment not intended for calculator use
Inappropriate use may result in disciplinary consequences. The teacher reserves the right to take steps to avoid inappropriate use by clearing the memory of the calculator, trading a personal calculator for a school calculator, or other measures as necessary.
