Questions about Measure It Twice

What does the Measure It Twice worksheet cover?

It practices deciding which unit is longer from two measurements of one object — 8 questions for Grade 2, all on Common Core 2.MD.A.2: Measure one object with two different units and explain why the two numbers differ. The instruction to students is “Answer each question”, and the answer key follows on the next sheet.

Which Common Core standard does Measure It Twice practice?

CCSS.MATH.CONTENT.2.MD.A.2 — 2.MD.A.2, under Measurement & Data for Grade 2. The published standard reads: “Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Measure It Twice is written for Grade 2, typically ages 7-8. It is one of the sheets on 2.MD.A.2, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Measure It Twice 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 Measure It Twice 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 Measure It Twice free to print and photocopy?

Yes. Measure It Twice, 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.
