Questions about Whose Is It?

What does the Whose Is It? worksheet cover?

It practices the possessive noun with an apostrophe and s — 8 questions for Grade 1, all on Common Core L.1.1: Use nouns, verbs, adjectives, pronouns and conjunctions correctly. The instruction to students is “Choose the word from the box that makes sense”, and the answer key follows on the next sheet.

Which Common Core standard does Whose Is It? practice?

CCSS.ELA-LITERACY.L.1.1 — L.1.1, under Language for Grade 1. The published standard reads: “Demonstrate command of the conventions of standard English grammar and usage when writing or speaking.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Whose Is It? is written for Grade 1, typically ages 6-7. It is one of the sheets on L.1.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Whose Is It? 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 Whose Is It? 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 Whose Is It? free to print and photocopy?

Yes. Whose Is It?, 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.
