Questions about Convert Time

What does the Convert Time worksheet cover?

It practises converting between days, weeks and years — 12 questions for Grade 4, all on Common Core 4.MD.A.2: Solve measurement and money word problems. The instruction to pupils is “Fill in the missing number”, and the answer key follows on the next sheet.

Which Common Core standard does Convert Time practise?

CCSS.MATH.CONTENT.4.MD.A.2 — 4.MD.A.2, in the Measurement & Data domain for Grade 4. The published standard reads: “Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

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

Does Convert Time 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 Convert Time 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 Convert Time free to print and photocopy?

Yes. Convert Time, 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.
