Which Math Courses and Topics Are Available on Mathplanet?

Updated

Mathplanet offers free high school math courses in four areas: Pre-algebra, Algebra 1, Algebra 2, and Geometry. That scope comes from the site's own description, which presents it as a free, accessible platform for learning mathematics. If you are looking for calculus, statistics, or test-prep material, those subjects are not listed in the available description, so confirm current coverage on the site before relying on it.

The four courses at a glance

Course Typical level What it usually covers
Pre-algebra Late middle school to early high school Arithmetic foundations, fractions, decimals, ratios, basic equations, and an introduction to variables
Algebra 1 High school Linear equations and inequalities, graphing lines, systems of equations, polynomials, and factoring
Algebra 2 High school, after Algebra 1 Quadratic functions, complex numbers, exponential and logarithmic functions, sequences, and advanced factoring
Geometry High school Points, lines, and planes; triangles and congruence; circles; area and volume; coordinate geometry; and introductory proofs

The level labels reflect how these course names are normally used in U.S. high school curricula. The site describes itself as offering high school math, which matches this sequence. Exact lesson lists and ordering may differ, so check the course pages for the specific topics included.

Who this scope fits

  • High school students who need a structured review or a supplement to classroom instruction in one of these four courses.
  • Middle school students preparing for algebra who want to work through Pre-algebra material at their own pace.
  • Adult learners returning to math who want to rebuild foundations before moving on to more advanced subjects.
  • Homeschool families looking for a free resource aligned with standard high school math topics.

Who should look elsewhere

Because the described catalog stops at these four courses, the platform is not positioned as a full math curriculum. Consider other resources if you need:

  • Calculus, statistics, or discrete math — not named in the site description.
  • Standardized test preparation such as SAT or ACT math review — not listed.
  • College-level or proof-based mathematics beyond introductory geometry reasoning.

How to check whether a topic is covered

  1. Open the site and go to the course list.
  2. Select the course closest to your level — for example, Algebra 1 if you are working on linear equations.
  3. Review the chapter or lesson index for that course.
  4. Match the lesson titles against the topic you need; if the topic is absent, the course does not cover it.

A quick way to test fit: pick one specific skill you need, such as solving systems of equations or finding the area of a circle, and see whether a lesson with that title exists before committing study time.

Practical notes

  • The platform is described as free, and no pricing information appears in the available site description. That does not by itself confirm every feature is unrestricted, so verify access when you arrive.
  • The site is in English, which matters if you are learning in another language.
  • Course names follow a standard U.S. sequence, so students from other systems should map topics rather than rely on the labels alone.
