Graphing Calculator Requirement for Certain Math Courses

SPRING 2021: The Chatfield Senior High School Math Department is selling NEW TI-Nspire graphing calculators to students at a lower price than can be found in stores. We also have some calculators avaiable for rent. If you are interested in purchasing or renting for the 2021-2022 school year, please fill out the form by the end of May using the following link:
Fees will be assess in September and calculators will be delivered to students in their math class as the beginning of the school year. 

A TI-Nspire CX II graphing calculator (non-CAS) is required for all math courses at the Algebra 2 level and higher if a student is taking the "traditional" track of math courses. For students taking the "skills" track of math courses, a graphing calculator is required at the Intermediate Algebra level and higher. (See the flowchart of math courses below.)

Students will need to have their calculators the first day of class. These calculators may be purchased online or at many local stores and discount warehouses. Students who qualify for the free or reduced lunch programs should see their math teacher in August. Students are encouraged to engrave their names on their calculators. The CSH math teachers will have an engraver available during the first two weeks of school.

CSH requires graphing calculators for many classes for the following reasons:
1. The state and county math standards require students to use the technology.
2. Assignments depend on students having access to a graphing calculator both in class and at home.
3. Students are required to use a graphing calculator on two of the four sections of the AP Calculus tests and all sections of the AP Statistics exam.
4. The SAT and the ACT college entrance tests permit the use of graphing calculators.

Please save technology rewards point symbol on the back of the retail package card from any new calculator purchase and give it to a math teacher in August.

Transforming the Task - AMPED and GiC

Beginning in the fall of 2019, we are excited to offer two new course which focus on transforming the task in student learning:

AMPED - Algebra I with Manufacturing Processes, Entrepreneurship, and Design
AMPED students will operate a business running an advanced fabrication lab customizing textile products and manufacturing other items comprised of wood, metal, and/or plastic. The proceeds generated from the business aspect of the problem will be utilized to self fund the venture and provide philanthropic opportunities for students through community service or monetary gifts to local charities.

GiC - Geometry in Construction
GiC students will be taught Geometry through real world, project based lessons, labs, and activities creating a richer, more robust learning environment for students. Students work on developing and understanding the skills necessary to thrive in the modern workplace including working in teams for both the math side and construction side.

Math Department Seeking Texas Instruments Technology Rewards Points
If you purchase a Texas Instruments Graphing Calculator for your student, the math department would like the technology rewards points symbol from the back of the retail package card. With these points, we can qualify for free technology items from Texas Instruments for Chatfield Senior High School. Give the points to any math teacher. Thank you.
