Fractions Game
Fraction Fleet is a free fractions game for grades 3-5, played in a web browser on a desktop or laptop, with no account, no sign-in and nothing to install. One click per skill. Fraction Fleet opens with only that skill in play: the targeting scope shows a fraction, a picture or a sum, and the student moves the target lock onto the one ship in the formation carrying the matching answer and fires. No two ships ever share a value, so there is exactly one right answer. Miss one and the game shows the fact, then asks it again a little later.
Pick a skill, press play
Name the fraction
A pie or bar shows a fraction; shoot the ship that names it. 3.NF.A.1.
Play name the fractionEquivalent fractions
2/4 = 1/2, 3/6 = 4/8. Every formation has exactly one equal fraction. 3.NF.A.3, 4.NF.A.1.
Play equivalent fractionsCompare fractions
Shoot the largest or the smallest fraction in the formation. 3.NF.A.3, 4.NF.A.2.
Play compare fractionsOr one denominator family
Pictures, equivalent fractions and comparing, on only these denominators.
Or a whole grade
Grade 3 fractions
Pictures, equivalent fractions and comparing, with the denominators Common Core grade 3 uses (2, 3, 4, 6, 8).
Play this setGrade 4 fractions
Adds adding and subtracting with like denominators and fraction-decimal matches, on the grade 4 denominators (2, 3, 4, 5, 6, 8, 10, 12).
Play this setGrade 5 warm-up
Review before unlike denominators. The game itself only adds and subtracts with like denominators.

Your own mix, one link for the class
The link opens Fraction Fleet with just that mix. Saved settings on a student's computer are left alone.
A skill that cannot be built from the denominators you tick is skipped for that round: decimals need 2, 4, 5, 8 or 10, simplifying needs a fraction that reduces to another ticked denominator (6/8 needs 4), and equivalent fractions need two ticked denominators that share a value (2 and 4, 3 and 6).

Questions teachers ask
- Is it free?
- Yes. Fraction Fleet is one of the 12 games on the Arcade Deck, which is free to play with no account and nothing to install. The ten rooms on the Promenade are for members; nothing on this page needs one.
- What do students need?
- A desktop or laptop computer with a keyboard (arrow keys move the target lock, space or enter fires; clicking a ship works too) and an up-to-date browser.
- Can I pick the denominators?
- Yes. Tick the denominators and the skills in the picker above and you get one link that opens Fraction Fleet with that mix. It needs at least two denominators so there are wrong answers to shoot past. The mix lives in the link itself; we do not store anything.
- Does it go too fast for younger students?
- It opens on Rookie, the slowest setting, with three ships. Difficulty comes from more ships to read, not from faster ships. Teacher Setup in the game changes the speed and turns the after-a-miss lesson on or off.
- Which standards does it cover?
- Each skill above names the Common Core code it practises. Adding and subtracting is like denominators only, and decimals are the exact ones from halves, fourths, fifths, eighths and tenths, so it does not cover unlike denominators (5.NF.A.1) or hundredths.
- Do students sign in, or does it collect anything?
- No sign-in and no student accounts. There are no ad trackers. See the privacy page for the details. Privacy.
- Who makes Starship Arcade?
- Starship Arcade is a small independent studio in Ontario. The games are built with AI and tested before they ship.
