Chatfield Senior High School Math Course Flowchart

Placement Exams

Students transferring in from a school outside of the Chatfield articulation area or outside of Jeffco may need to take a placement exam. We will reach out to students who need to complete a placement exam after they have registered with our counseling office.

Honors and Advanced Placement

Honors courses are availabe in Geometry, Algebra II, Pre-Calc/Trigonometry, and Math Analysis. Advanced Placement (AP) courese are offered in Calculus AB, Calculus BC, and Statistics.

Dual Enrollment College

Dual enrollment college credit is offered for Algebra III (College Algebra), Inferential Probability and Statistics (aka Statistics), and during the second semester of AP Statistics.

Graphing Calculator Requirement for Certain Math Courses

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 above.)

Students will need to have their calculators every day. 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.

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.
