Questions about Rounding and Estimating

What does the Rounding and Estimating worksheet cover?

It practises using rounding to check a calculation — 12 questions for Grade 5, all on Common Core 5.NBT.A.4: Round decimals. The instruction to pupils is “Round each number”, and the answer key follows on the next sheet.

Which Common Core standard does Rounding and Estimating practise?

CCSS.MATH.CONTENT.5.NBT.A.4 — 5.NBT.A.4, in the Number & Operations in Base Ten domain for Grade 5. The published standard reads: “Use place value understanding to round decimals to any place.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Rounding and Estimating is written for Grade 5, typically ages 10-11. It is one of the sheets on 5.NBT.A.4, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Rounding and Estimating 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 Rounding and Estimating 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 Rounding and Estimating free to print and photocopy?

Yes. Rounding and Estimating, 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.
