Dear Families of Students at Prairie Ridge High School,
The purpose of this letter is to inform you of our calculator recommendation if you are looking to purchase a new graphing calculator. TI has recently released the NSpire CX II and NSpire CX II CAS, both of which have some amazing capabilities. If you already own a graphing calculator, please do not feel the need to buy a new one. However, if you are in geometry or higher, then we are strongly encouraging you to consider purchasing the CX II or CX II CAS. With proper care, these devices can last through college and beyond.
These calculators function more like computers than calculators and provide the ability to perform calculations, create and manipulate graphs and spreadsheets, create or run simulations, collect data, learn computer coding, and a host of other opportunities. Research has shown that these calculators help to improve test scores on such assessments as the ACT, SAT, and AP Exams. Some researchers have gone so far as to say that students who do not have one are at a competitive disadvantage. The newest model, the TI-Nspire CX II has a color display and rechargeable batteries.
The CX II CAS has enhanced capabilities and is recommended to students planning to pursue a pathway to engineering. The CX II is a very powerful device as well, but does not contain some of the advanced capabilities that will be useful in higher-level math courses. Both devices are allowed on all AP and SAT exams; however, one primary drawback to the CX II CAS is that it is NOT allowed on the ACT, so please keep that in mind. The CX II (non-CAS) is allowed on the ACT.
For those of you who are interested in purchasing this calculator (IT IS NOT REQUIRED, but strongly recommended), we would like to make it as simple as possible. Therefore, we would like to offer the opportunity for you to purchase a TI-Nspire CX calculator as an addition to your registration fees. Through this offer, the cost of the CX II calculator is $130, and the CX II CAS is $132 In stores or online, the cost will likely be more. There are two options to our offer:
Option #1: Order between July 7th and July 31st for delivery to your son or daughter (in their math class) during the first two weeks of school. Orders will be placed through our vendor on 7/31, so the date your child will receive their device is dependent on their shipping times.
Option #2: Order by the end of the first week of school (August 14th) for delivery to your son or daughter (in their math class) during the first month of school.
Whether or not you decide to take us up on this registration offer, we would request that you send your proof-of-purchase card on the back of the packaging to school with your son or daughter so that our school might earn some additional equipment from Texas Instruments. The calculator also comes with student software they can load on a home computer, it is unfortunately not Chromebook compatible.
To expedite this process, you can pay through the Prairie Ridge web store, (https://chsd155.revtrak.net/RW-PRHS-Activities/)
