From idea to KDP upload
What you get
KDP book interior mode
Build a whole workbook in one PDF: 8.5 × 11 in, 8 × 10 in or A4 trim, no bleed, mirrored margins with the correct inside margin for your page count, and page numbers.
Up to 200 worksheets per book
Choose how many worksheets go in the book. A title page and a compact answer key at the back are added for you.
Built-in KDP checklist
A panel checks your trim size, page count (24 minimum), margins, smallest text and fonts, so you know it's ready before you upload.
Print-ready PDF, not a screenshot
A true vector PDF at the exact page size, with fonts embedded and no images to blur.
Unlimited new versions
Click "New Version" for a fresh set of problems with the same settings. Every version has a short code, so you can recreate a book later.
Levels for ages 5–10
Pick the child's age and Easy, Medium or Hard. Levels follow Common Core grade expectations, from Kindergarten to Grade 5. A plain-English card tells you what problems you'll get.
All four operations + Mixed
Addition, subtraction, multiplication, division, or a mix of them on the same page.
Answer key for every worksheet
Answers are calculated by the tool, so they're always right. Problems are checked automatically: no dividing by zero, no negative answers, no messy division.
Horizontal and vertical problems
Number facts across the page, multi-digit problems stacked in columns, and long division with working space.
Clean, kid-friendly pages
Large easy-to-read numbers in a font designed for young readers. Black and white, printer-friendly, with name/date/score lines.
Also great for printables
Switch to Printable mode for single worksheets on US Letter or A4, with answer keys. Print straight from the tool, or sell the PDFs as printables.
Live preview, works offline
Settings on the left, your worksheet on the right. Unzip the folder and double-click one file: no install, no account, and your work stays on your computer.
Good to know before you buy
Free worksheet websites are great for printing a quick page at home. This tool is built for the book side: a complete KDP interior in one PDF, with the right margins for your page count, page numbers, an answer key and a ready-to-upload check. It makes the interior only. You still create your own cover, title and KDP listing.
The earliest levels (like "add within 5") only have a small set of possible problems, so some repeat. Higher levels give new problems every time. This version covers arithmetic drills only: no fractions, decimals, negative numbers or word problems. Amazon expects each book to be different from the others, so give every book its own level, focus and title.
