Sums to 10, sums to 20, 2-digit and 3-digit addition — with or without regrouping. Shuffle a fresh set and print it with the answer key.

Addition is the first real arithmetic most kids meet, and the fastest way to make it stick is short, frequent practice with problems pitched at exactly the right level. This generator gives you that level dial: start withsums to 10 while your child is still counting on fingers, move tosums to 20 once they know their doubles and “make ten” pairs, and then step into column addition with 2-digit and 3-digit numbers.
The regrouping switch matters more than it looks. When kids first learn to stack numbers, the new skill is lining up the ones and tens — carrying a 1 on top of that is too much at once. Print a fewno regrouping sheets until the column layout is automatic, then flip towith regrouping, where every problem is guaranteed to need at least one carry so there is no way to coast through.
Twenty problems in four columns fits a ten-minute warm-up; drop to twelve problems in three columns for younger students who write big. Shuffle once per row of desks and every student gets a different sheet with the same difficulty — handy for keeping eyes on their own paper — and each set prints with its own answer key page, so checking is quick even with thirty different sheets. The set number in the footer of the form tells you which key belongs to which sheet.
Keep sessions short and end on a success: one sheet, checked together, a sticker on thereward chart. Timing is optional — accuracy first, speed later. If a particular fact keeps tripping them up, make a quickmissing-number sheetfor the same range: seeing 7 + ▢ = 12 next to 7 + 5 = ▢ builds the fact from both directions. And when addition feels solid, the matchingsubtraction worksheetsuse the same levels so nothing feels new except the sign.
Kindergarten: sums to 10. First grade: sums to 20, then sums to 100 and 2-digit without regrouping. Second grade: 2-digit with regrouping and 3-digit without. Third grade: 3-digit with regrouping. When a sheet takes under ten minutes with few mistakes, move up.
Regrouping (carrying) is when a column adds to 10 or more, so a 1 is carried to the next column — 47 + 35, for example. The “no regrouping” levels only produce problems where every column stays under 10, so kids can practice the column layout first.
Yes — press Shuffle problems. Every set is different and comes with its own answer key, so you can hand out a different worksheet to each student or print a week of practice at once.
Untick “Include answer key” before pressing Print worksheet. Tick it again to print a key later — the set number stays the same until you shuffle.
