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 which group has more 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.
Which group has more?
🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌🍌The answer is <. A child who answers > probably chose the smaller one.
Which group has more?
🌸🌸🌸🌸The answer is =. A child who answers < probably read them as the same.
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.
