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.
