A night sand floor. A slate shows a division fact. Sand molds spin on a turntable. Drag the ladle and dump the melt into the mold that is the quotient before the heat dies. Built for third- and fourth-grade division fact fluency — one-digit divisors, moving gates, no multiple-choice strip.
Read the Slate
The charge ticket shows a fact like 48 ÷ 6. The mold you want is the quotient, 8.
Watch the Table
Sand molds turn under the rail. The one under the ladle lights up. That is the gate you will hit if you dump now.
Pour
Drag the ladle, then release when the right number is under the spout. Eight good pours win the floor. Three cold or wrong pours end the run.
Stay Hot
The heat bar shrinks. If it empties before you pour, that charge is lost.
A Turning Floor
Numbered sand molds ride a foundry turntable. The right gate does not sit still. You have to pour while the table is moving.
Drag the Ladle
The melt hangs on a crane rail. Drag it, then let go over the mold that answers the slate. A hit quenches. A miss spatters sand.
Heat Dies
Each charge has a heat bar. Wait too long and the melt goes cold — a miss. Facts have to come fast.
Three Charges
Easy uses ÷2, ÷5, and ÷10 on a slow table. Medium adds ÷3, ÷4, ÷6, and ÷8. Hard mixes the facts and spins faster.
Sprue Gate is a third- and fourth-grade division game. A foundry slate shows a fact. Kids drag a ladle and dump melt into the spinning mold that is the quotient. That is fact fluency on a moving floor, not a row of answer buttons.
The Answer Moves
The right mold will leave the spout. Kids have to know 36 ÷ 4 while the table is still turning.
Dump, Don't Tap a Card
The control is a ladle on a rail. Correct and miss change the sand — quench or spatter — not just a green label.
Heat Makes It Fast
A dying heat bar stops stalling. Fluency has a clock without a quiz timer overlay.
Touch First
The ladle is a large grab. Mute sits with the iron score row, not under the fullscreen button.
The quotient. If the slate says 45 ÷ 5, dump into the mold marked 9. The other numbers are decoys — sometimes the divisor or a neighbor.
Press the ladle, drag it along the rail, and let go. The melt hits the mold that is closest under the spout.
That charge is a miss. You lose a heat. Three misses end the run. Eight good pours win.
Which divisors show up, how fast the table spins, and how quickly the heat dies. Hard mixes facts through 9 and 12.
Third and fourth grade (about ages 8–10), when students lock in one-digit division facts. Stay on Easy for ÷2, ÷5, and ÷10.
