In our world of growing technology, it is essential that students learn to work with and adapt to a variety of tools. The LCHS Math Department regularly utilizes graphing calculator technology to enhance lessons and provide more access to advanced mathematical thinking. We highly recommend that each student have his or her own graphing calculator for use during and outside of class, when deemed appropriate by his/her math teacher. Since we feel it is important for students to develop strong mental math and reasoning skills, there will be times when students are not permitted to use a calculator.

Our Algebra I, II, and Geometry teachers primarily use Desmos as their only calculator.  Other course teachers use the TI-83, TI-84 Plus, TI-84 Plus Silver Edition or the TI-Nspire (with TI-84 face plate) calculators along with Desmos. We recommend that students use one of these calculators so that our teachers will be able to help quickly with trouble-shoot problems and provide consistent instruction on using the graphing calculator technology. All of these calculators are permitted on most standardized tests including theSATs, SOLs, and AP Exams.

Students taking AP Calculus AB, BC, or AP Statistics may want to purchase the TI-89 Titanium or the TI-Nspire CAS because these calculators are equipped to deal with the advanced topics in these courses.

To find more information about these calculators, you may want to visit education.ti.com and click on the “Products” tab. These calculators are available at most electronics stores, office supply stores, or can be found on eBay.
