High School math curriculum

The complete high school math curriculum can be primarily completed through advanced, average, and remedial lesson plans.

Advanced math courses

In the advanced math courses, students complete Algebra 1 by 7th or 8th grade (middle school). Subsequently, they complete Geometry by grade 9 (freshman year), Algebra 2 by grade 10 (sophomore year), and Pre-calculus by grade 11 (junior high school year).

In the senior or final high school year, they can learn advanced math concepts and lessons like trigonometry, Calculus I and II, and prepare for AP calculus (AB & BC) or AP statistics.

The advanced math lesson plan covers more deeper and challenging concepts than basic lesson plans. Students who are interested in pursuing a career in STEM (science, technology, engineering, and mathematics) can go for this lesson plan.

Average math courses

The average high school math courses cover Algebra 1 by grade 9 (freshman year), Geometry by grade 10 (sophomore year), Algebra 2 by grade 11 (junior high school year), and Pre-calculus or trigonometry fundamentals in grade 12.

Average math lesson plans cover the standard math concepts that high school students need to succeed in their academic and professional lives. These lesson plans are designed for students who may or may not be pursuing a career in STEM, but they are still beneficial for students in all majors.

Remedial math courses
