Questions about Longest and Shortest

What does the Longest and Shortest worksheet cover?

It practices picking the longest or shortest of three objects — 8 questions for Kindergarten, all on Common Core K.MD.A.2: Put two objects side by side and say which is longer or heavier. The instruction to students is “Answer each question”, and the answer key follows on the next sheet.

Which Common Core standard does Longest and Shortest practice?

CCSS.MATH.CONTENT.K.MD.A.2 — K.MD.A.2, under Measurement & Data for Kindergarten. The published standard reads: “Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Longest and Shortest is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.MD.A.2, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Longest and Shortest 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 Longest and Shortest 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 Longest and Shortest free to print and photocopy?

Yes. Longest and Shortest, 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.
