How to use the generator
- Choose the operation and the number size. 2-digit plus 2-digit is the grade 2 standard; 2-digit plus 1-digit comes first; 3 and 4 digits follow in grades 3–4. The bottom number never has more digits than the top one.
- Decide about regrouping. "Every problem" for the week the step is taught, "Some problems" once it is known (children must look before they carry), "None" for the mechanics of column work.
- Pick the number of problems and versions. 20 leaves room to write carries; 50 is a fluency check. Up to four versions, each with its own answer key.
- Download or print. The PDF is built in your browser. Copy the link to get the same sheet again.
Which sheet for which grade?
Grade 1: 2-digit plus 1-digit, then 2-digit plus 2-digit without regrouping. Grade 2: 2-digit with regrouping, then mixed, then 3-digit (Common Core 2.NBT.B.5, 2.NBT.B.7). Grade 3: 3-digit with regrouping to fluency within 1000 (3.NBT.A.2). Grade 4: 4-digit numbers (4.NBT.B.4).
Why a generator?
Every sheet is new, so a child who has seen the answers once cannot reuse them; the link rebuilds the same sheet for a make-up or a parent; and the answer key is computed from the same numbers, so it is always right for the page in your hand. The Regrouping control is the part fixed PDFs cannot offer: the same page with the step forced, mixed in or removed.
