A Teachers Pay Teachers listing is not a puzzle book. The buyer is a teacher (or a seller who sells to teachers) paying for one activity page they can hand out tomorrow, plus a clean key they can trust.
The board is a 3×3 addition cross sum: nine circles, digits 1 to 9 once each, six printed totals. It is not a drill sheet of forty identical sums. It is not a sudoku. The mixed math shelf is already written: TPT math puzzle worksheets covers Ikura next to Smart Numbers and Number Blocks. This page is the Ikura file only. Do not rewrite that umbrella.
Ikura is the generator. This article is the classroom file. How the puzzle works is already written in How Ikura Puzzles Work. Stay out of the solve steps here unless the listing is sold as a lesson. A generate walkthrough for this module is not live on the site yet — do not send readers to a create URL.
One activity, one key
They are buying time. One student page. One separate answer key. The key is the nine digits filled in. A title that names the job (3×3 addition warm-up, given-digit logic) beats “fun math puzzles” with a mixed grab-bag.
They are not buying a title page, a table of contents, or enough puzzles to feel like a paperback.
Match the preview to the grade story. Easy boards (five givens) are a warm-up. The arithmetic stays small — no printed total exceeds 24 — so the hard part is the logic, not the sums. Sparse boards (two givens or fewer) are a proper sit. Do not stamp an early-years grade on a Hard page. Do not invent a grade band the listing cannot keep.
Every published board has one solution. Put that on the key, not as a speech in the student directions.
US letter is the default expectation. Do not silently ship a 6×9 book page. Type and the circle outlines have to survive a classroom copier.
On TPT the buyer is buying TPT’s own resource license, not a school or commercial license you attach to the listing. The default is an Individual License: one teacher, their own classroom. Extra colleagues need additional licenses. If you want to grant extra rights, write them as seller-authored terms in the listing, on top of TPT’s license.
Worksheets are not interiors
A KDP Ikura book (ikura-puzzle-book-kdp) is a different product: trim, page count, Look Inside. Same board. Wrong file for TPT. Do not upload the book PDF and hope.
Keep the settings that make the page fair (how many digits are given, whether the leftover-digit rail prints). Drop the book chrome. Put the key on its own sheet so a teacher can print 28 puzzles and one key.
Puzzle Book Studio is the assembly tool for books. A single worksheet may never need it.
The four-channel map is the product-form article. An Etsy pack (ikura-printables-etsy) is a short themed download. This is the classroom page.
This listing is still the PDF. Online play is live on this module: Productivity Interactive exports JSON and HTML for the BookPublisherTools WordPress plugin or a self-hosted player. Lifetime license, per product — see the editions page. A default catalog is a menu. A finish-screen button is only there if you opted into a leveled game under Catalog Merge → Game Options. Do not sell the TPT file as an LMS. That extra is already written: Online Playable Ikura for Website. Upload steps live in Publish a Puzzle Catalog.
Commercial rights for finished puzzles on Teachers Pay Teachers are part of the Puzzle Maker Pro license as stated on the homepage. That is not a substitute for TPT’s content rules.
The whole point
A TPT Ikura worksheet is one 3×3 addition-logic page plus a separate key. Name the warm-up, keep the drill sheets and the sudoku on other listings, and stop before it turns back into a book.
