IXL vs SOMATH vs Kumon NYC: An Honest Comparison for Parents (2026)
Three very different ways to do math outside school in NYC. An honest side-by-side on teaching model, pricing, results, and when each is right — written by SOMATH (School of Math), 226 W 79th Street, Upper West Side.
Short answer. IXL is a self-paced adaptive app your child uses alone at home ($10-20/mo). Kumon is a franchise worksheet program with light center supervision (~$150-200/mo per subject). SOMATH is a small-group teacher-led math school with six-student cohorts, in-person on the Upper West Side, taught by real teachers ($246-$800/mo depending on the track). They are not three flavors of the same thing — they are three fundamentally different teaching models. Which one is right depends entirely on what your child actually needs: daily practice reinforcement (IXL), computational fluency drills (Kumon), or genuine problem-solving development with a teacher (SOMATH). Below, an honest side-by-side.
Full disclosure: this is written by the SOMATH team. We have real biases — we run a small-group school, so we naturally believe in small-group teaching. That said, we send families to Kumon or IXL when it is actually the better fit for their child. What follows is our best attempt at an honest comparison.

1. The three teaching models, honestly
The fundamental difference between these three options is not price. It is the teaching model. If you understand the model, the price, the results, and the fit follow naturally.
SOMATH — Small-group teacher-led math school Our Program
SOMATH operates like a school, not a service. Classes meet weekly at our Upper West Side classroom at 226 W 79th Street. Cohorts are age-and-level based (Little Newtons for K-2, Kid Einsteins for grades 2-4, Young Fermats for grades 5-8, plus SHSAT, SAT, AP, and pre-calculus tracks). Curriculum is teacher-designed and progressive across the year. New families start with a free 30-minute evaluation and a written diagnostic.
IXL — Self-paced adaptive software
IXL is a subscription web-and-app product used by millions of families and thousands of schools. A child logs in, picks a skill (or is assigned one), and answers problems. The algorithm gives easier or harder problems based on accuracy. Right answers earn points and awards. There is no explanation delivered by a teacher — if the child gets a problem wrong, IXL shows the correct steps and moves on.
Kumon — Franchise-based worksheet repetition
Kumon is a Japanese-origin franchise system with over 20 centers in NYC. Every child works through the same worksheet sequence at their own pace. The Kumon center is not primarily a classroom — it is a submission point. Actual work is done at home, daily, on worksheets. The instructor's role is to grade, monitor pace, and advance the child to the next worksheet level.
2. Side-by-side comparison
| SOMATH | IXL | Kumon | |
|---|---|---|---|
| Teaching format | Small-group class, in-person, teacher-led | Software, at home, self-directed | Worksheets at home + brief center visits |
| Class size | Max 6 students per class | N/A (solo) | Varies at center; solo worksheets |
| Live teacher | Yes, teaches every class | None | Brief center check-ins, mostly grading |
| Feedback on reasoning | Real-time, on-process | None — only right/wrong | Minimal — correct answer only |
| Curriculum design | Teacher-designed, progressive | Adaptive algorithm | Fixed franchise worksheet ladder |
| Best at | Problem-solving, reasoning, tests | Daily practice reinforcement | Arithmetic fluency, daily habit |
| Weakest at | Daily habit (only weekly meetings) | Explaining concepts, hard problems | Problem-solving, reasoning depth |
| Diagnostic | Free 60-min evaluation + written report | Automated placement quiz | Initial placement test at center |
| Time commitment | One 90-120 min class per week | 15-30 min daily | 20-30 min daily worksheets |
| Monthly cost | $246-$800 depending on track | $10-20 | $150-200 per subject |
| Best fit for | Child needing teaching + tests | Motivated child needing practice | Child needing fluency + daily habit |
3. Real pricing, all-in
Advertised prices and all-in prices are not the same. Here is the honest math.
SOMATH — all-in cost Our Program
SOMATH tuition is monthly and includes one class per week (60 minutes for Little Newtons, 90 minutes for Kid Einsteins, 120 minutes for Young Fermats, SHSAT, and AP/Honors). Rates:
- Little Newtons (K-2, 60-min): $246/month
- Kid Einsteins (grades 3-4, 90-min): $367/month
- Young Fermats (grades 5-8, 120-min): $489/month
- SHSAT prep: $587/month
- SAT prep: $640/month
- AP / Honors / Pre-Calc: $800/month
One-time registration fee: $99 at enrollment. All-in first-month cost for a Kid Einsteins student: $489 tuition + $99 registration = $588. Subsequent months: $489 flat. Workbooks and printed materials are included at no extra charge. Cancel any time with 15 days notice. Up to four weeks of free pause per year. One free make-up class per month.
IXL — all-in cost
~$9.95/month for one subject (Math OR ELA), ~$19.95/month for a family plan covering multiple children. No materials fees. Annual plans discount modestly. That is the whole cost. Time cost: 15-30 minutes daily on-screen, unsupervised. For families comfortable managing screen time and self-direction, IXL is genuinely inexpensive.
Kumon — all-in cost (NYC)
Manhattan and Brooklyn Kumon centers typically charge $150-$200 per month per subject. Add a one-time registration fee (~$50) and a materials/testing fee (~$30). If a child does both Math and Reading, monthly cost doubles. Extra time cost: 20-30 minutes daily of worksheet completion at home, plus two brief center visits per week. Parents often underestimate the at-home time commitment — a child who skips daily worksheets falls behind quickly.
4. IXL: what it does well and where it stops
Where IXL wins. For daily practice reinforcement of school-year curriculum, IXL is genuinely excellent. It has broad content coverage, works on any device, and gives a self-motivated child a way to log 15-20 minutes of math practice most days at almost no cost. For families whose child is doing well in school and just wants to stay sharp, IXL is often the right answer.
Where IXL stops. IXL teaches by exposure — if the child sees enough problems of a certain type, they get better at that type. It does not explain concepts in a satisfying way, and it does not diagnose reasoning errors. When the child gets a problem wrong, IXL shows the correct steps and moves on. If the child does not understand the correct steps, IXL cannot help. It is also purely a solo activity, which for younger children (K-5) tends to mean either constant parent supervision (which defeats the purpose) or shallow, distracted practice.
5. Kumon: what it does well and where it stops
Where Kumon wins. Kumon builds computational fluency and a daily-work habit better than any other program available in NYC. If your child needs to build arithmetic speed, memorize multiplication tables, or get comfortable with long division and fraction operations at speed, Kumon works. The daily-worksheet discipline itself teaches something valuable — showing up, doing the work, moving forward incrementally. For families whose primary concern is these outcomes, Kumon delivers.
Where Kumon stops. Kumon is worksheet repetition. It does not teach problem-solving, does not build genuine reasoning skill, and does not prepare students for tests that reward creative thinking (SHSAT, AMC 8, top-school interviews). A bright child in Kumon often plateaus after 6-12 months, works through worksheets on autopilot, and gets bored. Parents whose child is not building anything beyond speed after a year of Kumon are often disappointed. There is also very little real teaching — the center instructor grades and files worksheets; explanation of concepts is not the model.
6. SOMATH: what it does well and where it stops
Where SOMATH wins. Small-group, teacher-led, in-person teaching is the model that builds genuine mathematical thinking. A teacher who can see six students working on a problem in real time can watch reasoning, ask the exposing question, correct process (not just answers), and adjust on the fly. This is how top math programs everywhere work — from the best private schools to specialty math circles — because it is the only model that develops problem-solving skill. SOMATH runs this model for a targeted price point on the Upper West Side. Our SHSAT, AMC 8, and AP/Honors tracks reflect this: they are hard because the student is developing reasoning, not just accumulating problems.
Where SOMATH stops. SOMATH meets once a week. We do not check on daily practice. If a family needs daily accountability on top of weekly teaching, we typically recommend they add IXL for daily reinforcement — not as a substitute, but as a complement. We are also not the right fit for a child whose primary need is arithmetic drill; a child at that stage may do better with Kumon or a math-fact app until they are ready for problem-solving work. We are honest about this at the free evaluation — if a family arrives and the child needs something we do not do, we say so.
7. Which is right for your child
8. For SHSAT, AMC 8, and selective admissions
Families targeting selective NYC high schools — Stuyvesant, Bronx Science, Brooklyn Tech, or Hunter — or competition math like the AMC 8 face a specific question: which of these three prepares a child for the actual exams?
| Program | SHSAT prep | AMC 8 prep | Hunter test prep |
|---|---|---|---|
| IXL | No dedicated track. Content coverage only. | No. | No. |
| Kumon | No. Focus is arithmetic worksheets. | No. | No. |
| SOMATH | Yes. Dedicated SHSAT track. | Yes. AMC 8 problems in Young Fermats curriculum. | Overlapping content with SHSAT track. |
The SHSAT math section rewards reasoning under time pressure. AMC 8 rewards creative problem-solving on hard, non-standard questions. Neither is solved by more worksheets or more IXL practice at level. See SHSAT vs Hunter High School Test for the full breakdown of what these exams actually test.
9. Can you combine them?
- SOMATH + IXL — a good combination. IXL handles daily reinforcement (15 min/day) while SOMATH does the actual teaching, curriculum, and diagnostic work. Many SOMATH families run this combination. Cost: one SOMATH plan + ~$10/month IXL.
- SOMATH + Kumon — usually a conflict. Kumon's fixed franchise curriculum runs its own sequence which frequently pulls a child out of sync with what we are teaching. Most families who join SOMATH end their Kumon subscription within a month. If your child needs both a reasoning program and a fluency program, we can coordinate on drill work internally.
- IXL + Kumon — largely redundant. Both are self-paced fluency programs. Combining them mostly just doubles the at-home worksheet load without adding teaching. Rarely the right combination.
- All three — almost never necessary. Time and cost add up quickly, and the child ends up with three different curriculum sequences pulling different directions.
10. What the SOMATH free evaluation actually gives you
If you are considering any of these three options, the SOMATH free evaluation is a useful diagnostic even if you end up choosing something else. A qualified teacher meets with your child for 30 minutes at our Upper West Side classroom and administers a written diagnostic across arithmetic, algebra readiness, geometry, and (for older students) reasoning problems. Within 48 hours you get a written report identifying exactly where your child sits, what the gaps are, and what any of the three programs above would need to address. That report is yours to keep whether you enroll or not.
We built the evaluation this way on purpose. Families choosing between IXL, Kumon, and SOMATH often do so with very limited information about where their child actually is. A one-hour diagnostic and a written report changes that. If the report suggests your child would be better served elsewhere, we say so.
See if a SOMATH class is a fit for your child
We run in-person small-group classes on the Upper West Side, K–12, from Little Newtons in Grade 1 through AP Calculus and SAT Math in high school. Every family starts with a free 30-minute in-person evaluation and a written diagnostic within 48 hours — yours to keep whether you enroll or not.
11. FAQ
What is the difference between IXL, Kumon, and SOMATH?
IXL is a self-paced app used alone at home. Kumon is a worksheet franchise with light center check-ins. SOMATH is a small-group in-person teacher-led math school on the Upper West Side. Three fundamentally different teaching models.
How much does each cost?
IXL is roughly $10-20 per month. Kumon runs $150-200 per month per subject in NYC. SOMATH runs $246-$800 per month depending on the class, plus a one-time $99 registration fee (workbooks and materials included).
Is IXL enough on its own?
For a self-motivated student staying sharp on school-year math, yes. For a struggling student, competition prep, or SHSAT prep, no.
Is Kumon good for math?
Yes for computational fluency and daily habit. No for problem-solving, reasoning, or selective-test preparation.
How is SOMATH different?
Live teacher, small-group in-person class, teacher-designed curriculum, real-time feedback on reasoning. The teaching model itself is different, not just the price point.
Can I combine them?
SOMATH + IXL is a common and effective combination. SOMATH + Kumon usually creates conflict. IXL + Kumon is largely redundant.
Which is best for SHSAT or AMC 8?
Live small-group teaching. Neither IXL nor Kumon has dedicated tracks for these tests. SOMATH does.
Which is right for a struggling student?
A teacher, not a worksheet or an app. Book the SOMATH free evaluation to get a written diagnostic first.
Not sure which is right? Start with a free diagnostic.
The SOMATH free evaluation is a 30-minute in-person session at 226 W 79th Street plus a written report delivered within 48 hours. It tells you exactly where your child stands in math — useful whether you enroll at SOMATH, sign up for IXL, or go to Kumon. Yours to keep either way.
