Pick a Shift
Eight orders or survival with three lives. Easy uses halves, thirds, and fourths. Hard uses tenths and twelfths.
Count the Guests
Otters wait with empty plates. You will serve one ring to each of them.
Tap the Rings
Tap a kelp ring to plate it. Tap again to send it back. Stop when every plate is full.
Read the Fraction
Rings served over rings in the roll. The next order slides in.
See the Cuts
The kelp roll is sliced into equal rings. That count is the denominator. Every ring is the same size.
Serve the Guests
Each otter wants one ring. Tap a ring to send it to a plate. That count is the numerator.
The Fraction Appears
When every plate is full, 3/8 lights up. Too many rings is a miss. The extra ring does not stick.
Score You Chase
A clean serve starts at +100 and climbs with the streak. A perfect eight-order run adds a kitchen bonus. Best scores save per mode and difficulty.
Kelp Roll is an equal-parts fraction game. A roll is cut into equal rings. Students tap rings onto guest plates, then see the fraction of the whole they served. Buttons and labels follow the site locale.
Denominator First
Kids see the equal cuts before they name the fraction. The bottom number is how many rings make one roll.
Numerator Is Guests
One ring per otter. The top number is how many rings left the loaf.
Tap, Don't Type
No keypad. Serving is the answer. The digits appear after a clean plate.
A Score That Moves
Point pops and a streak make sharing a loaf feel like a dinner rush.
The bottom number is how many equal rings the roll was cut into. The top number is how many rings you served.
That is a miss. The extra ring stays on the loaf. The streak resets. In survival you lose a life.
Yes. Tap a served ring to put it back on the loaf before every plate is full.
How finely the roll is cut. Easy uses 2, 3, or 4 rings. Hard uses up to 12.
Second through fourth grade, when students name a fraction as parts of a whole. Third grade is the main fit.
