CTHS Mathematics Calculator Policy
A graphing calculator is required for all math courses. Our courses have exams that require the use of a graphing calculator and exams where the use of a calculator is prohibited. Students need to know how to do the math without calculators. It is equally important that they learn how to use the current technology as a tool for when the numbers and problems get really "ugly". It is a student's responsibility to obtain and bring the appropriate calculator each day. As a math department, we do not have any "classroom" graphing calculators to lend students, even on test days. Be sure to obtain the correct graphing calculator and bring it every day!
The following courses require a graphing calculator:
Algebra 1, Algebra 1X, Geometry, Geometry/Precalculus Honors, Algebra 2, Honors Algebra 2, Algebra 2/Precalculus Honors, Introductory/Intermediate College Algebra, College Algebra, College Trigonometry, AP Statistics, AP Calculus AB, AP Calculus BC, IB Math Studies 1/2, IB Math SL 1/2, IB Math HL 1/2.
TI-83, TI-83+, TI-84, TI-84+, TI-84+ C or the TI-Nspire (non-CAS). The "Silver Editions" of the calculators are more expensive because they hold more memory and come with more tools. "Silver Editions" are great but not necessary. These calculators cost between $99 and $120 new. They can be purchased used on Ebay/Craigslist for as little as $35.
Additional Notes about graphing calculators:
The math department will have about 200 of the TI-84 graphing calculators to rent out to students in Algebra 1, Geometry or Algebra 2, students in higher level courses are expected to have their own graphing calculator. The cost for rental is $25 per calculator for the academic school year. This is a limited supply available on a first come, first serve basis. Lease agreements can be downloaded from the math department website. Parents must sign the lease. There are provisions in the lease for students in financial need. See the lease agreement for details.
