The study of mathematics, like the Nile, begins in minuteness but ends in magnificence. - Charles Caleb ColtonDepartment Chairperson: Kevin O'Reilly
Welcome to the Mathematics Department Webpage. It is our hope that you will find answers to all of your mathematics course related questions here.
In accordance with the state standards, students taking mathematics courses at Seaford High School will encounter courses and lessons designed around the principles of focus, coherence, and rigor, while engaged in a Regents-level program. These principles require that, at each grade level, students and teachers focus their time and energy on fewer topics, in order to form deeper understandings, gain greater skill and fluency, and more robustly apply what is learned.
Coherence in the curriculum means progressions that span grade levels to build students’ understanding of ever more sophisticated mathematical concepts and applications. Rigor means a combination of fluency exercises, chains of reasoning, abstract activities, and contextual activities throughout the module. Students will gain better understanding of number sense and operations, algebra, geometry, trigonometry, measurement, and statistics and probability. Students taking mathematics courses will employ the appropriate technologies for their mathematics level. At various times, they will work cooperatively to solve more involved problems or to discover previously unfamiliar mathematical concepts.
The Mathematics Department is committed to providing a quality educational experience to all students through the use of lessons that allow students to develop their problem solving and critical thinking skills. Students at all levels will utilize appropriate technology including graphing calculators and computers.
