Questions about Find the Complete Subject
What does the Find the Complete Subject worksheet cover?
It practices naming the whole complete subject, not just its main noun — 8 questions for Grade 4, all on Common Core L.4.1: Use relative pronouns, progressive verbs, modal auxiliaries and correct adjective order. The instruction to students is “Circle the right answer”, and the answer key follows on the next sheet.
Which Common Core standard does Find the Complete Subject practice?
CCSS.ELA-LITERACY.L.4.1 — L.4.1, under Language for Grade 4. 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?
Find the Complete Subject is written for Grade 4, typically ages 9-10. It is one of the sheets on L.4.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.
Does Find the Complete Subject 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 Find the Complete Subject 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 Find the Complete Subject free to print and photocopy?
Yes. Find the Complete Subject, 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.
