Mathematics
Algebra 2
Master advanced algebraic concepts in this 11th-grade Algebra 2 course, covering functions, equations, trigonometry, probability, and statistics through interactive lessons and real-world applications.
About the course
Course Overview
Algebra 2 builds on the skills learned in Algebra 1 and Geometry to prepare students for higher-level math and a wide range of STEM pathways. Designed for most students in the 11th grade, this course deepens understanding of algebraic concepts while introducing new topics essential for college and career readiness. Students explore polynomial, rational, exponential, logarithmic, radical, and trigonometric functions, as well as sequences, series, probability, and statistics.
Through nine comprehensive modules, learners develop strong problem-solving abilities and mathematical reasoning skills by engaging with interactive readings, video tutorials, practice problems, and assessments. Real-world scenarios and STEM-focused applications connect abstract concepts to everyday problem-solving. Graphing technology is integrated throughout the course to help students analyze and interpret functions, data, and models.
By the end of Algebra 2, students will be able to identify and analyze multiple types of functions, solve complex equations, apply trigonometric identities, interpret data using statistical methods, and model real-world situations mathematically. This course provides a solid foundation for advanced math courses such as Precalculus and serves as a critical stepping stone toward success in college-level mathematics and science courses.
