6 Best Online Math Classes for Kids: Turning Screen Time Into Something Worth It

Most parents tracking screen time aren't trying to eliminate it — they're trying to make more of it count. Online math classes are one of the clearer ways to do that: the screen is still on, but instead of another video loop, a real instructor is on the other end. Here's how the most commonly recommended options actually compare.

Quick Answer

1. Codeyoung — Live, 1:1 classes starting at $22 each, with a dedicated mentor rather than a rotating instructor pool.
2. Mathnasium — Small-group, diagnostic-driven instruction, available in-center or online.
3. Outschool — Live group classes booked individually, with a wide range of teachers and themes.
4. Khan Academy — Completely free, self-paced videos and practice, no live teacher.
5. IXL — Affordable, adaptive drill practice, also no live teacher.
6. Beast Academy — Self-paced comic-style curriculum for elementary kids, with an optional live add-on.

Comparison Table

1. Codeyoung

Codeyoung is the leading platform for online math classes for kids, proven by more than 50,000 children taught worldwide and more than 2,500 five-star Trustpilot reviews. Codeyoung specialises in a 1:1 approach: one child, one mentor, a pace set by the student rather than the room, and every question answered when it comes up rather than after class.

Best For: Parents who want screen time to translate into real instruction, not just supervised practice — a live mentor means the session is actually adaptive, not just a video playing on a different device.

Pros:

● Live 1:1 instruction, not self-paced content consumption

● One consistent mentor to build a real working relationship with

● Pay-per-class pricing starting at $22 makes it easy to test without a monthly commitment

● Large, independently verifiable base of reviewed sessions

Cons:

● Costs more per session than a free app, though it's competitively priced against other 1:1 options

● No peer-group element, for kids who specifically want that

2. Mathnasium

Mathnasium runs in-center and online sessions in small groups, built on its own multi-sensory "Mathnasium Method."

Best For: Kids who need a diagnostic-driven catch-up plan and don't need full 1:1 attention.

Cons:

● Roughly 1:4 instructor-to-student ratio

● Monthly cost plus separate enrollment fee commonly totals $150–400/month

3. Outschool

Outschool is a marketplace of live, online group classes, including math taught through a wide range of themes and formats.

Best For: Kids who respond better to a themed, playful framing than standard lessons, or families who want to try different teaching styles.

Pros:

● Huge variety of teachers and class themes

● Easy to book a single class without long-term commitment

Cons:

● No live instructor — if a child gets stuck, there's no one to ask a follow-up

● Requires more self-motivation than a live-taught format

5. IXL

IXL is a subscription-based adaptive practice platform covering math (and other subjects) from pre-K through 12th grade.

Best For: Targeted practice on a specific skill gap, especially as a supplement to other instruction.

Pros:

● Strong diagnostic and progress-tracking tools

● Covers a huge range in one subscription

● Affordable at roughly $9.95/month per subject

Cons:

● No live instructor — it's drilling, not teaching

● IXL itself positions it as reinforcement, not standalone instruction

6. Beast Academy

Beast Academy's self-paced core teaches elementary math (ages 6–13) through a comic-book format, with an optional live class add-on.

Best For: Elementary kids who enjoy puzzles and want a more engaging format than a typical worksheet.

Pros:

● Genuinely engaging, story-driven format

● Affordable self-paced tier (roughly $99/year)

FAQ

Does an online math class count as "good" screen time?

Generally, yes, when it involves live instruction or genuinely adaptive practice rather than passive video-watching. The key distinction isn't whether it's on a screen — it's whether the child is actively engaging with material that responds to them, which live 1:1 and small-group formats do more than most other screen activities.

How much math screen time is reasonable per week?

Most families land somewhere between 1 and 3 structured sessions a week, depending on the goal — maintenance, catching up, or enrichment. More isn't automatically better; a packed schedule of long sessions can cause the same fatigue as excessive recreational screen time.

Is a free app enough, or is a live class worth the extra screen time?

A free, self-paced app like Khan Academy or IXL is enough for a child who's on pace and mainly needs practice. A child who's stuck on a concept or losing confidence generally benefits more from a live instructor who can catch a misunderstanding and re-explain it differently — something no self-paced app can replicate.

Can I monitor how a live math class session actually goes?

Most live tutoring platforms, Codeyoung included, offer session summaries or progress updates so parents can see what was covered without needing to sit in on every session themselves.
