Questions about Read and Write Four-Digit Numbers

What does the Read and Write Four-Digit Numbers worksheet cover?

It practises expanded form at four places — 12 questions for Grade 4, all on Common Core 4.NBT.A.2: Read, write and compare large numbers. The instruction to pupils is “Write each number in expanded form”, and the answer key follows on the next sheet.

Which Common Core standard does Read and Write Four-Digit Numbers practise?

CCSS.MATH.CONTENT.4.NBT.A.2 — 4.NBT.A.2, in the Number & Operations in Base Ten domain for Grade 4. The published standard reads: “Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Read and Write Four-Digit Numbers is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.NBT.A.2, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Read and Write Four-Digit Numbers come with an answer key?

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.

How many different versions of Read and Write Four-Digit Numbers can I print?

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.

Is Read and Write Four-Digit Numbers free to print and photocopy?

Yes. Read and Write Four-Digit Numbers, 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.
