A Mathematics Curriculum Study In Trigonometric Graphs To Align With The Common Core Standards

Abstract

The Common Core State Standards (CCSS) were written by The National Governors Association (NGA), in collaboration with the Council of Chief State School Officers (CCSSO) in 2010, and was adopted by 45 states in an attempt to nationalize the United States curriculum in English and mathematics. Now it is up to the states to implement new curriculum to align to these standards. In the third year of high school mathematics, students are introduced to radian measures and trigonometric functions, and these abstract mathematical topics can be difficult for them to learn. The lesson plans contained within this curriculum project are aligned to current CCSS related to trigonometric functions and modeling and are intended for teachers to use in their classrooms to visualize and model the basic trigonometric functions beginning with an introduction to radians, and including the functions sine cosine and tangent.
