The Gates Chili High School Mathematics Department offers 19 different courses, including Regents & Honors levels. 

The traditional Regents sequence of Algebra 1, Geometry, and Algebra 2 is currently in transition.  During the 2018-19 school year the incoming accelerated freshmen are piloting a sequence that takes them directly into Algebra 2, after completing Algebra 1 the previous year as 8th graders.  This group will then take Geometry the following year.  Based on the success of this pilot group, all incoming freshmen will transition to this new sequence in 2019-2020. 

Honors courses are designed to challenge students by including enrichment topics, quicker pacing, and a project requirement.  Students choose to either complete a research project and submit a written paper on a mathematics topic of their choosing, or participate in Monroe County Math League competitions once a month from October to February. 

Electives beyond the three NYS Regents courses include Advanced Topics in Math or Precalculus. 

Advanced Placement offerings are available in Calculus (both AB & BC) and Statistics.  Computer Science courses offered are Intro to CS and JAVA.

For students who require additional time to master course material, there are Introductory courses for Algebra 1 and Algebra 2.  

Alternative pathways that emphasis applied skills exist for students who do not wish to pursue an Advanced Designation diploma, and include Applied Geometry & Applied Algebra. College Algebra is an elective that is designed to ensure that graduating seniors are prepared to enroll in credit bearing courses at the college level, avoiding costly remedial math courses due to attrition or a decline in mathematics skills or concepts.   

All courses are taught with the aid of Texas Instruments Nspire CX graphing calculators, with each classroom equipped with a full class set of 30 units. Additional software or computer applications may also be used to demonstrate concepts in class or for HW support outside the classroom.
