How to Start Studying Math on Mathplanet

Updated

Mathplanet is a free platform for high school math, offering courses in Pre-algebra, Algebra 1, Algebra 2, and Geometry. To start, open the site, pick the course that matches your level, and work through its lessons in order at your own pace. The site is built for self-directed study, so there is no enrollment step described—you choose a subject and begin.

Step 1: Choose your course

The site organizes its math content by subject. The four advertised high school courses are:

  • Pre-algebra — a starting point if arithmetic and basic concepts need review
  • Algebra 1 — first formal algebra course
  • Algebra 2 — continuation of Algebra 1
  • Geometry — shapes, proofs, and spatial reasoning

Pick based on your current level rather than age or grade. If you are unsure, start with Pre-algebra and move forward when the material feels easy.

Step 2: Work through lessons in sequence

Each course is divided into topics and lessons. The intended path is linear: complete a lesson, then move to the next. Because the platform is self-paced, you decide how much to cover per session. A practical approach:

  1. Read the lesson explanation for one topic.
  2. Try the examples yourself before reading the worked solution.
  3. Move to the next lesson only when you can explain the concept without notes.

Step 3: Verify your understanding

Mathplanet's stated purpose is accessible math learning, but the site description does not detail a quiz or grading system. To check progress without built-in assessments, use these methods:

  • Redo examples cold — close the page and solve the lesson's examples from memory.
  • Explain aloud — state the rule or method in your own words; gaps in the explanation reveal gaps in understanding.
  • Cross-check with practice problems — if you need graded exercises, pair Mathplanet lessons with a problem set from another source.

What to expect and common sticking points

Situation What to do
Course feels too hard Step back one course (e.g., Algebra 1 → Pre-algebra)
Course feels too easy Skip ahead within the topic list, but confirm with the redo-examples check
No feedback on answers Use the self-check methods above; the site is lesson-based, not test-based
Device warning appears The site may show a "device not supported" message and ask you to rotate your screen—use a larger screen or landscape orientation

Who this suits

Mathplanet fits independent learners who want structured high school math explanations without a schedule or account requirement mentioned in the site materials. It is less suited to learners who need graded practice, teacher feedback, or a formal certificate—the platform's description centers on free course content, not credentialing.

Start with the course that matches your level, follow the lessons in order, and test yourself by reproducing each lesson's examples from memory before moving on.
