Answer questions. Open lunch boxes. Beat the boss.
Pick the grade you are in and the subjects you are learning. Choose a hero. Then run through a level knocking open backpacks, crayon boxes and lunch boxes — ten questions — before facing the boss guarding the door.
| Level | Room | You open | Boss |
|---|---|---|---|
| 1-1 | Playground | Backpacks | Rowdy Rubberthe kickball nobody put away |

Content is aligned to the standards most US states use, and every level is tagged with the standard it comes from.
Common Core, K–5. Counting through fractions, decimals, volume and order of operations.
Common Core ELA — phonics and word recognition through theme and author's purpose.
Grade-level spelling patterns plus the Dolch sight word lists.
Next Generation Science Standards, K–5.
A common elementary novice sequence, with the words read aloud.
A right answer sends your hero running up to knock the box open, and a coin pops out. A wrong answer opens it too — empty, and drained of color — and the run keeps going, so nobody gets stuck on one question. At the end of the ten, the boss re-asks what you just practised. Five correct answers beat it; three wrong and you try the level again.
Missed questions are listed with their correct answers when the level ends, which is the part worth reading over a kid's shoulder.
