Questions about Mixed Metric Conversions

What does the Mixed Metric Conversions worksheet cover?

It practises choosing the right factor from the units — 12 questions for Grade 5, all on Common Core 5.MD.A.1: Convert between units of measurement. The instruction to pupils is “Fill in the missing number”, and the answer key follows on the next sheet.

Which Common Core standard does Mixed Metric Conversions practise?

CCSS.MATH.CONTENT.5.MD.A.1 — 5.MD.A.1, in the Measurement & Data domain for Grade 5. The published standard reads: “Convert among different-sized standard measurement units within a given measurement system, and use these conversions in solving multi-step real world problems.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Mixed Metric Conversions is written for Grade 5, typically ages 10-11. It is one of the sheets on 5.MD.A.1, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Mixed Metric Conversions 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 Mixed Metric Conversions 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 Mixed Metric Conversions free to print and photocopy?

Yes. Mixed Metric Conversions, 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.
