🍕 Fraction Lab
Real fraction tiles, circles, and a fraction wall. Build, compare, and match.
How to play
- Pick a lab theme and a difficulty tier, then click Start Experimenting.
- Tiers 1 through 3: tap tiles to build the target fraction exactly.
- Tiers 4 and 5: tap the bigger fraction circle, or Equal if they match.
- Tier 6: find the fraction wall piece that matches the highlighted one.
- Earn 🧪 flasks for every challenge you solve to unlock new lab themes.
- No penalty for a wrong pick, just look again and try once more.
Fraction games built around real fraction manipulatives
Fraction Lab is a fraction game built directly around three classic fraction manipulatives instead of a single flat worksheet-style exercise. Most fraction tiles and fraction circles found online are static teaching aids you look at, not something you actually play with toward a scored goal. Fraction Lab wraps all three in short, self-contained challenges with a real lab theme, so building a fraction, comparing two fractions, or spotting an equivalent fraction each feels like a small experiment with a clear result instead of a worksheet problem.
The first three tiers use fraction tiles: a target fraction like 3/4 appears above an empty bar, and you tap tile pieces, starting with halves and quarters, then thirds and sixths, then a mixed set including eighths, until the bar fills to exactly the right amount. A tile that would overshoot the target simply won't add, so there's no way to get stuck with too much and no penalty for experimenting with different combinations along the way.
Tiers 4 and 5 switch to fraction circles: two pie-shaped circles are shaded to represent two different fractions, and the job is to tap whichever is bigger, or a separate Equal button when they genuinely match. Some pairs are deliberately equal even though they use different denominators, like one half and two quarters, which is exactly the kind of equivalent-fraction recognition that a lot of fraction games skip. Tier 6 then uses a classic fraction wall, a stack of rows for halves, thirds, quarters, and more all spanning the same width, and asks which fraction elsewhere on the wall lines up with a highlighted piece.
Every solved challenge earns flasks toward unlocking a new lab theme, from the starting Classic Lab through Space, Candy, Ocean, and Volcano labs, so there's a real reason to keep working through tiers beyond a raw score. Fraction Lab is free, works with a mouse, touchscreen, or keyboard, needs no download or account, and saves your progress locally in your own browser, which also makes it school-safe on a shared classroom device.

Frequently asked questions
How do I play Fraction Lab?
Pick a lab theme and a difficulty tier, then click Start Experimenting. Early tiers have you tap fraction tiles to build a target fraction, later tiers have you compare fraction circles or find a matching fraction on a fraction wall.
What is a fraction wall and how does it help?
A fraction wall stacks rows for halves, thirds, quarters, and more, all spanning the same total width, so you can see at a glance which fractions from different rows line up and are equal. Tier 6 uses this exact idea to ask which fraction matches a highlighted piece.
Is there a penalty for getting an answer wrong?
No. A wrong pick in the comparing or fraction wall tiers just asks you to look again with no score penalty, and in the tile-building tiers a tile that would overshoot the target simply won't add, so there's no way to get stuck in a bad state.
What ages is Fraction Lab good for?
Roughly ages 8 through 13, or grades 3 through 6. The first tiers use simple halves and quarters, while later tiers introduce thirds, sixths, eighths, and genuinely tricky equivalent fractions.
Does Fraction Lab cover equivalent fractions?
Yes. The fraction circle tiers include pairs that are exactly equal even though they look different, like one half and two quarters, and the fraction wall tier is built specifically around spotting equivalent fractions across rows.
