• Lenape Regional High School District Calculator Information

    Understanding that a comprehensive mathematics curriculum should help students learn to use calculators, computers, and other technological tools as a part of learning mathematics, the Mathematics Departments of the Lenape Regional High School District believe that calculator usage should be an integral part of mathematics education in our schools. The Technology Principle of the Standards document of the National Council of Teachers of Mathematics (NCTM) states: ". . . mathematics instructional programs should use technology to help all students understand mathematics and should prepare them to use mathematics in an increasingly technological world."

    The NCTM and New Jersey Student Learning Standards make it clear, however, that such tools do not replace the need to learn basic facts, to compute mentally, or to do reasonable paper and pencil computation. Calculators and computers with appropriate software can transform the classroom into a laboratory where students can investigate and experiment with mathematical ideas. We put forth the following information so that students, parents, and teachers will agree on the use of technology in the classroom: 

    1. We encourage the appropriate use of technology in the classroom. Students need to consider when the use of mental mathematics, paper and pencil, or a calculator is appropriate.

    2. The calculator requirement for all mathematics courses Geometry and beyond in this district is the Texas Instruments Nspire CX or CX II *Updated as of June 2020*.   The students' name should be engraved on the calculator and a record kept of the registration number.

    3. Understanding that the purchase of a graphics calculator represents a considerable expense to the student, the Mathematics Department agrees that a calculator purchased will be useful to the student throughout high school. Students will not be expected to purchase an expensive upgrade for a later course.

    4. Students will be required to show all work and be able to explain how they arrived at a solution on assignments.

    5. Students will be required to show understanding on tests with and without a calculator.

    6. Currently, graphing calculators are allowed on the PARCC, SAT, and Advanced Placement exams. Some colleges, however, do not allow calculators on their placement examinations and some do not permit their use in math classrooms.

    7. The calculator should not replace fundamental understanding.
