Graphing Calculator Requirement for Math Courses

"Use appropriate tools strategically:
Mathematically proficient students consider the available tools when solving a mathematical problem. For example, mathematically proficient high school students analyze graphs of functions and solutions generated using a graphing calculator. They are able to use technological tools to explore and deepen their understanding of concepts."
- Common Core Standards for Mathematical Practice

To prepare students to become proficient problem solvers, it is more important than ever that they understand how to use appropriate technology. In the past, a graphing calculator was not required until upper-level math courses. However, starting with the 2016-2017 school year, all Chatfield students will be using graphing calculators in their math courses. Students will be expected to have a TI-Nspire CX graphing calculator (the non-CAS version). Students will need to have their calculators the first day of class. These calculators may be purchased from Chatfield by May 20th, 2016. See below for purchasing information. Students who qualify for 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 weeks of school.

The CSH Math Department will be making a bulk purchase of TI-Nspire CX (non-CAS) graphing calculators in May 2017. 
Because these are part of a bulk order, they will be sold at a discounted price of $120. If you would like to benefit from these savings and order a calculator from us, please fill out this form and get a check delivered to Keri Brusven (Math Department Chair) by Friday, May 19th, 2017. Checks should be made out to Chatfield Senior High School for $120. Calculators will be delivered to students during the first day of class in August.

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.

Anyone having questions about this requirement is encouraged to contact Ms. Keri Brusven, Chatfield math teacher. She can be reached at

Please save the entire back of the retail package card (not just the technology rewards point symbol) from any new calculator purchase and give it to a math teacher in August.

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 entire back of the retail package card (not just the technology rewards points symbol). With this card, we can qualify for free technology items from Texas Instruments for Chatfield Senior High School. Give the card to any math teacher. Thank you.

Math Department Vision:
1. As a department, we are committed to supporting each other, collaborating regularly, teaching consistent standards, and enforcing consistent expectations.
2. As a department, we are committed to offering rigorous classes at all level so that all students are challenged and prepared to continue their education and function in their chosen career field.
3. As a department, we are committed to incorporating technology to produce forward-thinking students who are prepared for the 21st century.
4. As a department, we are committed to implementing innovative teaching strategies so students can efficiently and logically apply their math abilities to real world problems.
5. As a department, we are committed to teaching an enriched curriculum based on the Colorado Content Standards.

Characteristics of Mathematically Proficient Students
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
