Why does this matter for writing?

Because it is the toolkit behind every sentence type. Once a student can tell a dependent clause from an independent one, comma rules, fragments, and compound-complex sentences all become one idea instead of three.

Is a prepositional phrase the same as a phrase?

It is one kind. Under the gate is prepositional; running the last lap is a participial phrase; to check the boxes is an infinitive phrase. All of them are phrases, because none has a subject and verb pair.

How is this different from the clauses page for younger grades?

The fourth through sixth grade page sorts clauses into independent and dependent. This one adds the third answer, phrase, which is what CCSS L.7.1.a asks for and what makes the distinction usable.

7th grade phrases and clauses

7th grade phrases and clauses worksheets

A phrase is a group of words with no subject and verb pair inside it. A clause has both. An independent clause could be printed alone as a sentence; a dependent clause could not, because a word like because or although leaves it waiting. Seventh graders name which one a word group is.

The kind of sentences you'll fix

Write what each word group is. Choose from the words in parentheses.

“running the last lap in the rain” Phrase or clause: (dependent clause / independent clause / phrase).
Fixed: “running the last lap in the rain” Phrase or clause: phrase.
“the archivists catalogued every diary” Phrase or clause: (dependent clause / independent clause / phrase).
“the soil in the north bed drains poorly” Phrase or clause: (dependent clause / independent clause / phrase).

Every print pulls a new set of sentences at this level, so a make-up test or a second sibling gets a different mix.

What's on a 7th grade sheet

7th grade sheets draw from 42 sentences, 8 to a page. None of these sentences are on 8th grade sheets. 8th grade sheets print 7 to a page.

A few of the sentences:

before the reaction had finished
our captain scored in the final minute
the fort guarded the crossing for years

Fix it. Write what each word group is. Choose from the words in parentheses. 8 sentences to fix per page.

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Teach a two-question routine and keep it the same every time. First: is there a subject with its own verb? No means phrase, and you are done. Yes means clause, so ask the second question: could this be printed alone with a capital and a period? Yes means independent, no means dependent. Students who learn one question at a time stop guessing from length. The words that make a clause dependent are worth putting on an index card, because recognizing them on sight turns the second question into a one-second check.

Watch for: Length has nothing to do with it. Rain fell is a clause of two words; in the middle of a long grey afternoon is a phrase of eight. An -ing word does not make a clause. Running the last lap has no subject, so it stays a phrase. A dependent clause is a whole clause, not a broken one. It has a subject and a verb; what it lacks is permission to stand alone, and that comes from its first word (because, although, until, who, that).
