More sheets come with a subscription
The first sheet at every level is free. A subscription gives you a new sheet whenever you want one — and the part paper cannot do: five minutes of practice a day that adapts to your child, and a weekly email naming exactly what they are stuck on.
$5 a child a month, never more than $12 for the family. The first 7 days are free and need no card.

The mistakes behind most wrong answers
A wrong answer in adding and taking away fractions is rarely random. These are the ones that come up most often, each on a real problem — worth knowing before you mark a sheet, because the fix for each is different.
- 13+13=?
The answer is 23. A child who answers 26 probably changed the bottom number too.
- 38+18=?
The answer is 48. A child who answers 58 probably counted one too many or too few.
- 34−24=?
The answer is 14. A child who answers 54 probably added instead of taking away.
- 18+58=?
The answer is 68. A child who answers 48 probably took away instead of adding.
In the app, every wrong answer is matched against mistakes like these, and the weekly email tells you which one your child keeps making — in those words, not as a percentage.
