Multiplication Facts and Missing Factors
Dive a copper wreck in Treasure Diving. A hull plate shows a times fact with a gap — a missing factor or the product. Drag a numbered keg onto the empty belt socket. Seat the missing factor and the diver drops a fathom toward the chest. Third-grade multiplication fact fluency, with Haul points for every seated keg.

How to Play Treasure Diving
The dive starts
Treasure Diving starts on its own. Tap Easy, Medium, or Hard on the copper bar. There is no Play button over the kegs.
Read the hull plate
The plate shows a times fact with a gap. The prompt says Seat the missing factor. Read the hull plate. Drag a keg onto the empty belt socket.
Seat the missing factor
Drag the keg whose number completes the plate onto Seat here. A hit adds Haul and the plate teaches a × b is the product. A miss costs an air tank.
Drop eight fathoms to Chest line
Seat eight kegs to win, or keep going until the air tanks are gone. Chest line shows your Haul score, a rank, and Dive again.
Key Features
Hull-plate facts and missing factors
The rusted plate shows a × b with one seat empty. Easy leans on the product. Medium and Hard hide a factor. Drag a copper keg onto the empty belt socket. A hit clanks the keg in and drops the diver toward the chest. A miss recoils the keg and costs an air tank.
A wreck you sink through
Treasure Diving starts on its own. Easy, Medium, or Hard stay on the copper bar so you can switch the pitch without a menu. Each seated keg pays out the chain. Eight clean seats reach Chest line.
Haul score and streak
Each seated keg starts at 100 Haul and grows by 50 with a streak. Point pops fly off the keg. A miss resets the streak. A fathom gauge shows the drop toward the chest.
Difficulty that changes the skill
Easy uses facts 1 through 5 and two kegs. Medium opens 1 through 10, three kegs, and more missing factors. Hard runs 1 through 12, four kegs, and look-alike stamps next to the right seat.
What is Treasure Diving?
Treasure Diving is a third-grade multiplication game about facts and missing factors. Kids drag copper kegs on a dusk wreck and seat the missing factor on the belt socket. Easy stays on 1 through 5. Medium and Hard open the rest of the times table and hide a factor more often. The skill is fact fluency, not tapping a quiz card.
Why Play Treasure Diving?
Facts and missing factors
Third-grade math asks kids to know products and find a missing factor. Treasure Diving makes that a dive: read the hull plate, then seat the missing factor.
A race to the chest
Each seated keg drops the diver a fathom. The Fathom gauge fills. Kids feel the wreck getting closer when facts are fluent.
Instant copper feedback
A hit seats the keg and sprays Haul off the piece. A miss recoils. The board always uses Seat the missing factor, so the plate and the how-to say the same words.
Works on a finger or a mouse
Drag a keg onto the socket. Touch targets stay large, and the hot socket lights up while you drag.
