Set 1. Prints on its own sheet.

CCSS.MATH.CONTENT.4.NBT.A.1 — 4.NBT.A.1, in the Number & Operations in Base Ten domain for Grade 4. The published standard reads: “Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.” The worksheet assesses that standard rather than a paraphrase of it.
Ten Times Smaller is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.NBT.A.1, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.
Yes. All 12 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.
25 — one per pupil, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.
Yes. Ten Times Smaller, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
