Maths Is Fun: Is the Classic Math Site Still Worth Your Time in 2026?

Can a free worksheet site built back in 2002 still keep pace with how adults learn math today? Maths Is Fun has quietly taught kids and confused parents since then, without charging a single fee. Rod Pierce built it as a math teacher's side project, and it grew into one of the most visited homework references online.

National assessment data show nearly one in three American adults still struggle with basic numeracy. That gap didn't exist when the site was designed purely for classroom homework help. This review covers what platforms like Maths Is Fun do well, where they run out of road, and what helps once worksheets stop being enough.

Adults who want to keep learning math, or any other subject, need more than a static worksheet page built for kids. Nibble offers daily lessons across math and dozens of other subjects, built for a phone screen instead of a classroom desk. A single lookup becomes a daily habit instead.

Give the Nibble app a try and see how it fits into your day.

Short on time? These are the highlights worth knowing first.

• Maths Is Fun is a free website covering topics from basic counting through calculus.
• Rod Pierce created the site in 2002 and still runs it as a solo project today.
• Definitions, worksheets, and times tables make up its strongest content.
• Advanced topics like calculus get thinner coverage than basic arithmetic.
• No mobile app, no account system, and no progress tracking exist on the site.

Maths Is Fun, also known by its domain mathsisfun.com, is a free website built mostly for K-12 students, along with the parents and teachers who support them.

Rod Pierce, a math teacher, started the site in 2002 and still runs it independently today. He also built the related Mathopolis practice site around the same time.

The site organizes its content into sections like Numbers, Algebra, Geometry, Data, and Puzzles. There's also an illustrated math dictionary and a library of printable worksheets. A first grader counting on an abacus and a high schooler working through a tricky math problem can both find a page built for their level.

Everything is free, funded entirely through on-page ads rather than subscriptions. That model has kept the site running for over two decades without charging a single user.

🧠 Ads keep this site free forever. A Nibble subscription buys daily structure instead of banner space.

The site breaks down into a handful of core sections, each covering a different slice of math.

• The illustrated math dictionary offers plain-language definitions with diagrams for terms like "exponents" and "polynomial."
• Algebra and geometry lessons cover solving for x and working with angles.
• Worksheets and printables span 1st grade counting sheets, subtracting fractions, percents, and times tables.
• Basic statistics, probability, and graphing live in the Data section, built for early data literacy.
• Math puzzles and browser games bring in brain teasers and digital flash cards for drilling math facts.
• A teacher's page rounds things out with printable resources for a 4th grade classroom or younger.
• Coverage stays strong through arithmetic and early algebra, then thins out for higher-level or applied mathematics.

Readers looking for interactive tools built for graphing and geometry often reach for GeoGebra instead of the site's simpler math games.

🧠 One definition at a time only goes so far. Nibble pairs each lesson with a quiz right after.

The entire site costs nothing, and no premium tier or paid version exists behind a paywall. Every page runs on ads, with a simple show-ads or hide-ads toggle built right into the page for anyone who finds banners distracting.

There's no signup wall either, so a visitor can jump straight into a lesson without creating an account or verifying an email.

Nothing here needs an upgrade, since the free tier already includes every lesson, worksheet, and puzzle on the site.

• It's free, with no hidden costs or upsells anywhere on the site.
• The site has run continuously for over two decades, which is rare for an independent project.
• Looking up a definition mid-homework takes seconds, thanks to the illustrated dictionary.
• Classroom teachers and parents can use it as a supplement to instruction, not a replacement for it.

• There's no mobile app, so browsing depends on a mobile browser at best.
• No account system or progress tracking exists, ruling out any kind of streak.
• Support for topics beyond core K-12 math stays thin.
• Some older game elements rely on outdated tech that doesn't render on every device.
• Flashcard-style tools like Quizlet alternatives cover other subjects better than a static worksheet page.

🧠 A streak counter and saved progress make a five-minute session easy to pick back up. The Nibble app builds both in from day one.

Get started

Independent reviewers generally praise the site's clarity and its usefulness as a homework supplement. Most agree it works best alongside classroom teaching, not as a standalone curriculum.

Several reviewers note that the advanced material feels thinner than the beginner content. A few also mention that the page layout feels dated on a small screen, with text and diagrams sized for a desktop monitor rather than a phone.

That lines up with a resource built mainly around K-12 fundamentals: great for a quick answer, not built to carry someone through years of learning.

This site is built for K-12 students working through homework, parents helping out at the kitchen table, and teachers who need a quick worksheet or classroom reference. All three groups get real value from it.

Homeschooling parents lean on it especially heavily, since the explanations don't assume a teacher is standing nearby to clarify a tricky step.

Adults who've finished school and want ongoing, varied learning fall outside that group entirely. Flashcard apps like Brainscape cover some of that gap for other subjects, though math itself still needs a broader home once school ends.

🧠 A homework supplement doesn't carry anyone past graduation. The Nibble app picks up right where school leaves off.

Maths Is Fun answers a single question well, but adults chasing an ongoing habit need something built for repeat visits, not one-off lookups.

Nibble isn't a math-drilling tool, and it doesn't aim to replace a math curriculum. It's built for adults who want a daily habit of learning math, mixed with everything else that keeps a curious mind interested.

A dedicated Math & Logic topic track covers lessons, puzzles, and games on both percents and logic problems. An AI tutor feature also lets a reader chat directly with a simulated historical figure about a topic, which makes a one-way lesson feel more like a conversation.

Daily sessions and a streak system replace the open-a-page-close-a-tab pattern. Lessons come as text, video, audio, or games, depending on what fits the moment. Readers coming from coding-focused apps like Sololearn will recognize the phone-first format.

Every lesson lands in a personalized feed based on past interests. That means less digging through menus for something worth reading, and daily streaks keep the momentum going without feeling like a chore. A morning coffee break might surface a five-minute lesson on percents, while a bedtime session offers something on ancient history instead.

Topics span math, logic, history, art, and psychology instead of one subject alone. Readers who explored soft-skill microlearning through a site like SmartyMe will notice a similar bite-sized structure applied across more subjects.

🧠 Text, video, audio, and games all live inside the Nibble app, ready whenever the mood strikes.

The trade-off between a narrow reference tool and a daily habit shows up again in comparisons like Nibble vs Imprint. A student cramming for tomorrow's quiz still wants the free reference. An adult looking to build a standing learning habit generally picks the broader option instead.

🧠 One subject sits behind this whole site. Nibble opens the door to 25-plus more.

Maths Is Fun still earns its place as a quick reference for a homework question or a forgotten definition. Rod Pierce built something that lasted over two decades without charging a single user. But a worksheet page was never designed to build a lasting habit.

Nibble picks up where a static reference leaves off, with personalized recommendations, daily streaks, and lessons built for a phone screen. Spare minutes on a commute or a coffee break become a short lesson instead of another scroll through a feed. Math sits alongside history, art, and dozens of other subjects.

None of this replaces a classroom or a textbook, and it isn't meant to. It simply gives an adult reader a reason to keep learning once school, and the worksheets that came with it, are long finished.
