Questions about Order Three Lengths

What does the Order Three Lengths worksheet cover?

It practices ordering three measured objects by length — 8 questions for Grade 1, all on Common Core 1.MD.A.1: Put objects in order from shortest to longest. The instruction to students is “Answer each question”, and the answer key follows on the next sheet.

Which Common Core standard does Order Three Lengths practice?

CCSS.MATH.CONTENT.1.MD.A.1 — 1.MD.A.1, under Measurement & Data for Grade 1. The published standard reads: “Order three objects by length; compare the lengths of two objects indirectly by using a third object.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Order Three Lengths is written for Grade 1, typically ages 6-7. It is one of the sheets on 1.MD.A.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Order Three Lengths come with an answer key?

Yes. All 8 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 Order Three Lengths can I print?

25 — one per student, 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 Order Three Lengths free to print and photocopy?

Yes. Order Three Lengths, 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.
