Best Online Math Classes for Kids in 2026: Codeyoung vs. Beast Academy, AoPS, Outschool, Khan Academy & Mathnasium

Our editorial team evaluated the leading online math programs for kids, scoring each on five factors that matter most to parents — using publicly available Trustpilot ratings, listed pricing, and documented program features, not paid or sponsored placements. Where a program has no public review aggregate (AoPS/Beast Academy), we note that instead of estimating a number.

Our Rating Methodology

  • Live Instruction & Personalization — live, real-time teaching vs. self-paced with no feedback loop
  • Curriculum Depth & Grade Coverage — grade range, and how deep the material goes
  • Reviews & Reputation — published consumer review scores and recurring parent feedback
  • Value for Price — cost relative to what’s delivered
  • Platform Experience — quality and reliability of scheduling, class platform, and practice tools

The Top Online Math Programs for Kids of 2026

Rank Program Overall Live Instruction & Personalization Curriculum Depth & Grade Coverage Reviews & Reputation Value for Price Platform Experience Format
1 Codeyoung ★★★★☆ (4.4) 4.8 4.4 4.5 4.0 4.3 Live, 1-on-1
2 Outschool ★★★★☆ (4.3) 4.3 4.2 4.5 4.3 4.3 Live, marketplace (1:1 & group)
3 AoPS / Beast Academy ★★★★☆ (4.1) 4.2 4.7 N/A* 3.5 4.2 Self-paced (elementary) + live (advanced)
4 Mathnasium ★★★☆☆ (3.7) 3.6 3.6 4.0 3.2 3.6 Online + in-person hybrid
5 Khan Academy ★★★☆☆ (3.5) 2.0 4.5 3.5 5.0 3.5 Self-paced, free

*AoPS/Beast Academy has no public consumer-review aggregate comparable to Trustpilot; it’s independently reviewed by curriculum evaluators (e.g., Common Sense Education, homeschool review sites), which consistently praise its depth but note cost-over-time as a downside. That qualitative record informed its other category scores rather than a numeric Reviews & Reputation score.

Codeyoung

Codeyoung earned the highest overall rating, driven primarily by its live, 1:1 instruction model and a 4.5-star Trustpilot rating built on genuine review volume. Classes are taught by certified mentors and personalized in real time, covering School Math (aligned to US Common Core, GCSE, CBSE, and ICSE), Vedic Math, and Logical Reasoning across grades K-12. It’s STEM.org accredited, with mentors averaging 5,000-7,500+ teaching hours.

Best for: Families who want live, curriculum-aligned 1:1 instruction rather than a self-paced or group format.

Reviewers note: Parents consistently praise mentor quality and how well lessons adapt to a child’s pace. Recurring criticism in reviews centers on scheduling mix-ups, a strict cancellation policy, and inconsistent quality among newer mentors — worth asking about directly before enrolling.

Outschool

Outschool is the closest competitor to Codeyoung on overall rating, matching it on Reviews & Reputation with its own 4.5-star Trustpilot score across roughly 3,200 reviews, and edging ahead on Value for Price thanks to its flexible, pay-per-class model. As a marketplace of independent live educators, it covers PreK through grade 12 in both 1:1 and group formats.

Best for: Families who want live classes without a long-term commitment, and who are comfortable evaluating individual teachers.

Reviewers note: Reviewers frequently cite engaging instructors and flexible scheduling. A smaller but notable set of complaints, concentrated on a separate review platform (Sitejabber), center on refund and cancellation-policy disputes — a pattern worth checking against a specific teacher’s individual policies before booking.

AoPS / Beast Academy

AoPS and its elementary arm, Beast Academy, score highest on Curriculum Depth & Grade Coverage of any program on this list, built specifically for advanced and mathematically gifted students. Beast Academy Online (ages 6-13) is self-paced, while AoPS Academy’s live Virtual Campus (grades 2-12) adds small-group instruction and competition-math preparation.

Best for: Gifted or advanced students who find grade-level math too easy and want genuine challenge, including competition prep.

Reviewers note: Curriculum reviewers consistently praise its depth and conceptual rigor. The most common caution is cost — AoPS Academy’s live courses run $715-825 per semester, and reviewers note that sustained use “could get a bit pricey over time.”

Mathnasium

Mathnasium’s rating reflects a program that’s well-established but inconsistent across its network of independently run centers. It offers a genuine diagnostic-driven approach and the flexibility to move between online sessions and an in-person center, but its 4.0-star Trustpilot rating comes with real caveats.

Best for: Families who want the option to switch between online sessions and a local, in-person center.

Reviewers note: Parents report strong results and rapport with individual tutors, but reviews also flag inconsistent tutor quality between locations, a worksheet-heavy method that can feel non-interactive, and monthly costs (often $300+) that some reviewers view as high relative to results.

Khan Academy

Khan Academy scores highest on Value for Price by a wide margin, simply because it’s entirely free. It also scores well on Curriculum Depth & Grade Coverage, spanning kindergarten through calculus. Its lower overall rating reflects the tradeoff inherent to any free, self-paced platform: no live instruction at all, and a 3.5-star Trustpilot rating (from a comparatively small sample of 85 reviews) that cites a non-interactive format as a recurring frustration.

Best for: Families who want a genuinely free, self-paced supplement to independent or classroom learning.

Reviewers note: Reviewers consistently praise the free, high-quality content and clear explanations. The most common complaint is the non-interactive format — several reviewers specifically flag having to restart an entire lesson after a single incorrect answer, and note limited depth for advanced material.

A Note on Methodology and Limitations

These ratings are our own editorial assessment based on publicly available data, not a paid placement, sponsorship, or certification from any program listed. Review scores cite Trustpilot where a program has a public presence there; where they don’t (AoPS/Beast Academy), we relied on the qualitative record from independent curriculum reviewers instead of assigning a number we couldn’t source. Pricing and features reflect what’s publicly listed as of mid-2026 and can change — we’d encourage any parent comparing these programs to verify current pricing directly with each provider before enrolling.
