Here is what happens behind every Printipus math page, so you know exactly what you are handing to a child.
Levels you can trust
Each page sticks to one skill at one level, like "addition to 20" or "3-digit subtraction with regrouping", and shows the grade and Common Core standard it fits.

Rules for the problems
- "Without regrouping" really means no carrying or borrowing anywhere; "with regrouping" means every problem needs it.
- Every level has a fixed answer range, so numbers never jump beyond what the level promises.
- Division pages divide evenly unless a page says otherwise.
- On mystery pictures each color covers several answers, so the picture cannot be guessed without doing the math.
Keys that always match
The sheet and its answer key come out of the same calculation at the same moment. Nobody types the key by hand, so the two can never disagree.
Our own artwork
All pictures are drawn in the Printipus style: thick outlines, closed shapes and a friendly face wherever it fits. Bits too small for a problem arrive already colored.
Pages do not change
A page always shows the same problems, so a sheet printed today matches the one you print next month, and the key still fits.
