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 word problems 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.
Kai has 15 cards. Mia has 18. How many more does Mia have?
The answer is 3. A child who answers 4 probably counted one too many or too few.
Noah has 3 shells. Kai has 9. How many more does Kai have?
The answer is 6. A child who answers 9 probably answered with one of the numbers shown.
Ava has 7 blocks. Ivy has 1. How many more does Ava have?
The answer is 6. A child who answers 8 probably added instead of taking away.
Lucas has 2 buttons and gets 3 more. How many now?
The answer is 5. A child who answers 1 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.
