Calculators at Eaglecrest

A graphing calculator is now required for all math classes at EHS.  Our courses have exams that require use of a calculator and exams where the use of a calculator ​​​is prohibited.  Students need to know how to do the math without a calculator but it is equally important that they learn how to use the current technology for when the numbers and problems get "ugly".

​It is the student's responsibility to obtain and bring the appropriate calculator each day in good working order.  As a math department we do not have any "classroom" calculators to lend to students, even on test days, and we do not have extra batteries to give out.  Students are not allowed to share calculators during a test or quiz so please be sure to acquire the correct calculator and bring it every day!

Calculator Requirements

Students must obtain one of the following Texas Instruments models:

TI-83, TI-83+, TI-84, TI-84+ or the TI-Nspire (non-CAS version)

These calculators cost between $99.00 and $150.00 new but can often be purchased used on Craigslist, eBay, Amazon or at Goodwill for as little as $35.00.  ​The "Silver Editions" of the calculators are more expensive because they hold more memory and come with more tools.  "Silver Editions" are great but are not necessary.

Rental Information

​The math department has about 300 of the TI-84 graphing calculators to rent to students at a cost of $25.00 per rental for the academic year.  This is a limited supply available on a first-come, first served basis.  Download the ​Lease Agreement Here or pick a form up at the bookroom.  A parent signature is required on the lease.  There are provisions in the lease for students in financial need.  See the lease agreement for all details.
