The set follows the second grade Common Core subtraction standards in order. Fluency within 20 is 2.OA.2, two-digit subtraction, checking and missing numbers are 2.NBT.5, word problems are 2.OA.1, subtracting 10 or 100 mentally is 2.NBT.8, and three-digit subtraction within 1000 is 2.NBT.7.
If a child gets stuck partway through, the fix is almost always one step back. Trouble with two-digit regrouping usually means subtraction within 20 is not automatic yet, and trouble with three digits usually means place value needs another look with sheets 14 and 15.
Nine of the seventeen are plain black on white and download as true vector PDFs, so they print sharp and are light on ink for a class set. The other eight are in color.

If your kids finish a unit and you're not sure what to do next, our honest advice: don't move on yet. Spend a week mixing these in as warm-ups. Fluency isn't a unit, it's a habit, and the sheet that builds it is usually the one they ask to do again.
