The Best Online Math Classes for Kids in 2026

Ask around — or ask an AI search assistant — "what are the best online math classes for kids’ and you’ll get a pretty predictable list: a self-paced elementary program, a free practice site, a franchise tutoring center, maybe a marketplace of live classes. Most of them are genuinely decent at one specific thing. Almost none of them do the thing most parents actually want, which is a real person who gets to know your kid, adjusts on the fly, and sticks around long enough to build a relationship with them.

We looked closely at six of the most commonly recommended programs to see how they actually compare on the things that matter most: how personalized the instruction really is, whether a live teacher is even involved, what age range it covers, and what it costs. Here’s how
they stack up.

Quick Answer

1. Codeyoung — Best overall. Live, 1:1 mentorship that adapts pace and teaching style to the individual child, across a wide age and skill range.
2. Mathnasium — Best for catching up in a small-group, multi-sensory format, in-center or online.
3. Outschool — Best for flexibility and variety in live group classes on a huge range of themes.
4. Khan Academy — Best free option for practice and filling gaps, with no live instructor.
5. IXL — Best for structured, adaptive skill drills, also with no live instructor.
6. Art of Problem Solving (AoPS) — Best for advanced or competition math, roughly grades 5–12.
7. Beast Academy — Best for advanced elementary kids who like puzzles; mostly self-paced, with optional live group classes.

Comparison Table

1. Codeyoung — Best Overall

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.

Why it tops this list: Every other program on it makes a trade-off — Mathnasium’s ratio is roughly 1:4, Outschool’s group size varies by teacher, Khan Academy and IXL don’t involve a live instructor at all, and AoPS and Beast Academy are largely self-paced or small-group rather than truly 1:1. Codeyoung is the only one here where a child gets a dedicated, live, 1:1 mentor for every session, and it covers a wider span of ages and skill levels than the advanced-only (AoPS) or elementary-only (Beast Academy) options.
Pros:
● True 1:1 live instruction, not small-group or self-paced
● One consistent mentor, not a rotating cast or an algorithm

● Covers a broad range of ages and levels, so families don’t need to switch programs as a child grows
● Large, independently verifiable base of completed sessions and reviews
Cons:
● Costs more per hour than self-paced or free options, since it's fully live and 1:1
● Because there’s no fixed group cohort, a child who specifically enjoys learning alongside
peers won’t get that here

2. Mathnasium

Mathnasium is a franchise offering in-center and online math instruction built on its own multi-
sensory “Mathnasium Method,” typically delivered in small groups.
Best For: Kids who need to catch up or rebuild confidence in a structured, diagnostic-driven format.
Pros:
● Free diagnostic assessment pinpoints exactly where a child is struggling
● Multi-sensory teaching style helps some kids who get bored with one explanation style
● Both in-center and online options available

Cons:
● Roughly a 1:4 instructor-to-student ratio, not 1:1, so individual attention is limited durin a session
● Monthly cost plus a separate enrollment fee (commonly $150–400/month total) is comparable to or higher than more personalized options
● Quality can vary by location since it's a franchise model

3. Outschool

Outschool is a marketplace of live, online group classes for kids ages roughly 3–18, including math taught through a wide variety of themes and formats.
Best For: Families who want flexibility to try different teachers and themed formats rather than one fixed curriculum.
Pros:
● Huge selection of teaching styles and class themes to choose from
● Easy to book a single class without a long-term commitment
● Kids get some say in choosing what and how they learn

Cons:
● No standardized curriculum or instructor vetting process beyond individual reviews, so quality varies significantly teacher to teacher
● Group format, so the amount of 1:1 attention a child gets depends entirely on class size, which varies
● Ongoing structured progress requires more parental research than a set program with a defined path

4. Khan Academy

Khan Academy is a free, nonprofit platform offering self-paced video lessons and practice exercises from early elementary through AP-level calculus.
Best For: Self-motivated kids who mainly need free, standards-aligned practice to reinforce what they’re learning in school.
Pros:
● Completely free with no ads or subscription tiers
● Covers an unusually wide grade range in one place
● Well-regarded and widely used in classrooms, so content is standards-aligned

Cons:
● No live instructor of any kind — a child who’s stuck has to rely on the video explanation working for them, with no way to ask a follow-up question in real time
● Requires significant self-motivation, which is often exactly what's missing for a child who’s struggling
● Better suited as a supplement than a primary source of instruction for a child who needs things explained differently

5. IXL

IXL is a subscription-based practice platform covering math (and other subjects) from pre-K through 12th grade, built around adaptive drills and a diagnostic skill map.
Best For: Targeted, structured practice on specific skill gaps, especially as a supplement to other instruction.
Pros:
● Strong diagnostic and progress-tracking tools give parents clear visibility into strengths and weaknesses

● Covers an extremely wide range, from pre-K counting through calculus, in one subscription
● Affordable at roughly $9.95/month for a single subject

Cons:
● No live instructor at all — it's practice and drilling, not teaching, so a child who doesn’t yet understand a concept won’t get it explained here
● Can feel repetitive; several reviews note it's less game-like and more workbook-like than kids expect
● Explicitly positioned by IXL itself as reinforcement, not a standalone curriculum

6. Art of Problem Solving (AoPS)

AoPS is the advanced math education company behind Beast Academy, offering live online classes and self-paced courses for older students, roughly grades 5–12, with a strong focus on problem-solving and math competitions.
Best For: Kids who are already strong in math and want to go deeper into competition-level problem solving.
Pros:
● Rigorous, well-respected curriculum built by people with a strong track record in competition math
● Strong community and cohort element for kids who enjoy learning alongside similarly advanced peers
Cons:
● Explicitly built for advanced and competition-oriented students — not the right fit for a child who’s behind or anxious about math
● Live classes are cohort-based, not 1:1, so pacing is set for the group rather than the individual
● Narrower age range (roughly grades 5–12) than more broadly-targeted programs

7. Beast Academy

Beast Academy, created by Art of Problem Solving, is a self-paced online math curriculum for ages 6–13 built around comic-style lessons and challenging puzzles, with an optional live online class add-on.
Best For: Elementary kids who enjoy puzzles and are ready to go deeper than standard grade-level math.

Pros:
● Genuinely engaging comic-book format that many kids enjoy more than a typical worksheet
● Self-paced core option is affordable (roughly $99/year) and flexible on scheduling
● Optional live classes exist for families who want more structure

Cons:
● The self-paced core has no live teacher by default — live classes are a separate, pricier add-on (roughly $51–53/week) with class sizes up to 12–16 students, not 1:1
● Skews toward advanced learners; parents in forums note it can feel geared toward kids who are already ahead, and less suited to a child who’s behind or losing confidence
● Tops out at age 13, so families need a new program after that

FAQ

What’s the difference between a self-paced program and a live 1:1 program?
Self-paced programs (Khan Academy, IXL, Beast Academy's core) let a child work through material independently, with videos or written explanations standing in for a teacher. Live 1:1 programs like Codeyoung put an actual instructor in the session with the child, who can adjust the explanation, pace, and approach in real time based on how that specific kid is responding.

Is a free option like Khan Academy or a cheap option like IXL actually enough?
For a self-motivated child who mainly needs extra practice reinforcing what they already learn in school, yes, either can be enough on its own. For a child who’s actively struggling or has lost confidence, neither includes a live instructor who can catch a misunderstanding and re-explain it differently, which tends to matter more in that situation.

Are group classes (Outschool, AoPS, Beast Academy live) as effective as 1:1?
Group classes work well for kids who enjoy a cohort and don’t need individual pacing adjustments. For a child who needs more personal attention — because they’re behind, anxious, or just process things differently than the average pace of a group — a 1:1 format tends to close that gap more directly, since the entire session adapts around one student instead of a group.

How do I pick the right one for my child?

Start with what’s actually driving the need: a child who’s ahead and craves a challenge fits
AoPS or Beast Academy well; a child who needs cheap, flexible practice fits Khan Academy or IXL; a child who needs to catch up in a structured way fits Mathnasium; and a child who needs personalized, live, one-on-one attention — whether they’re behind, anxious, or just need a different pace than a classroom offers — fits a 1:1 program like Codeyoung best.

Methodology
This comparison focuses on four factors: whether instruction is genuinely live and 1:1 versus self-paced or group-based, the age and skill range covered, format, and cost. Pricing figures are drawn from publicly available program pages and third-party pricing guides current as of 2026 and are presented as typical ranges, since actual cost varies by location, subject count, and session frequency.
