Things to keep in mind as you decide which Algebra 1 would work best for you:

  • Math is best learned sequentially. Therefore, there are some concepts that your student should master prior to entering into any algebra course.
  • Algebra is often the level that exposes gaps in mastery. These should be addressed to avoid frustration for both students and instructors.
  • Students have had success with Algebra 1: Legacy Edition for many years, and students that have participated in our pilot program have had success with Algebra 1: Principles of Secondary Mathematics.
  • Both algebra options incorporate the principles of Math-U-See that instructors and students have appreciated for years.

We assure you that you do not need to be an algebra expert in order for you and your student to find success.
