Algebra 2 reviews and builds on topics discussed in Algebra 1. Topics introduced in Algebra 2 provide an introduction to topics that will be presented in more rigorous college prep math courses. This course emphasizes expanding critical thinking and problem-solving skills. Using technology as a tool is incorporated into the course.
Semester 1 topics include working in the complex number system, a review of sequences and series are introduced. Quadratic, polynomial, and radical functions are graphed and solved. The study of systems of linear equations is expanded to non-linear systems.
Semester 2 explores exponential, log and trig functions. Students will simplify and graph these functions by hand and using technology. Students will model real world data with functions. Data collection methods, central tendency and dispersion are presented. The normal curve is studied. Two-variable data sets are analyzed and the function of best fit is determined and used to make predictions.
This course is intended only for students recovering previously lost or failed credits. Students and parents/guardians are responsible for ensuring that the student is eligible to take this course for credit recovery and that it meets school or district requirements. This course will be listed on the transcript as Credit Recovery.
This course requires practice on GeoGebra and/or Desmos. These are both online free tools. In addition Graph paper may be needed for assignments.
