Order Fractions With Like Denominators
A sunlit dye stall, glass jars, and a wooden crate. Each jar is a strip model of a fraction with the same denominator. Pick a jar up and set it on the crate from least full to most full. Wrong seats slosh. Eight crates win a run. Built for fourth-grade ordering fractions.

How to Play Dye Rack
Read the Jars
Jars on the table show fractions such as 2/7 and 5/7. Same denominator. The shorter dye fill is the smaller fraction.
Pick One Up
Drag a jar onto the wooden crate. Least full goes in the left bay. Most full goes in the right bay.
Keep What Seats
A correct drop scores and stays. A wrong bay sloshes the jar back and costs a life.
Clear Eight Crates
Fill every bay to dry a crate. Streaks add fifty a pop. Three sloshes close the stall.
Key Features
Glass Strip Models
Every jar is the same height. The dye fill is the numerator. Students compare how full the jars are.
Set Them on the Crate
Pick a jar up and drop it in a bay. Left is least full. Right is most full.
A Slosh Is a Miss
A jar in the wrong bay rocks back to the table. The ones already seated stay put.
Three Stall Speeds
Easy seats two jars. Medium adds a third. Hard lines up four tight fills.
What is Dye Rack?
Dye Rack is a fourth-grade fractions game. A market stall holds glass dye jars. Each jar is a strip model of a fraction with a shared denominator. The player sets the jars on a crate from least full to most full. Ordering numerators is moving bottles, not ticking boxes.
Why Play Dye Rack?
Fill You Can See
Dye height is the numerator. Students order by looking at the glass, then check the tag.
Like Denominators
A shared denominator makes the rule plain: fewer filled rings means a smaller fraction.
Hands on the Crate
Jars are picked up and set down. Wrong seats splash back. The stall changes on every drop.
Touch First
Jars and bays are large. The mute plate sits with the score row, not under the fullscreen control.
Frequently Asked Questions
Which jar goes on the left?
The least full jar — the smallest fraction. That is the shortest dye fill.
How do I move a jar?
Press and drag it onto a crate bay. Drop it in the bay that matches its order from least to most.
What if I put a full jar on the left?
It sloshes back to the table. That costs a life. Jars already seated stay in the crate.
What do Easy, Medium, and Hard change?
How many jars sit on the stall. The least-to-most rule stays the same.
What grade is this for?
Third through fifth grade (about ages 8–11), when students compare and order fractions with like denominators. Stay on Easy for two jars.
