Clauses and Phrases Worksheet Ideas for Grades 3 to 7
A clauses and phrases worksheet helps students see how a sentence is built from smaller parts and why some groups of words are complete while others are not. This guide explains the difference, gives tested examples and offers practice ideas for the classroom.
The difference between a phrase and a clause
A clause is a group of words with a subject and a verb. A phrase is a group of words that works together as a unit but does not have both a subject and a verb.
Compare these groups of words:
- after school is a phrase. It has no subject and no verb.
- the bell rang is a clause. The subject is “bell” and the verb is “rang”.
- running across the field is a phrase. It has a verb form, “running”, but no subject.
- when the rain stopped is a clause. The subject is “rain” and the verb is “stopped”.
The last example shows why this topic needs practice. “When the rain stopped” has a subject and a verb, but it does not make sense alone. That brings us to two kinds of clauses.
Independent and dependent clauses
An independent clause can stand alone as a complete sentence. A dependent clause cannot. It depends on an independent clause to finish its meaning.
- Independent: “We finished the test.”
- Dependent: “because the bell rang”
Dependent clauses often begin with a word such as because, when, although, if, while, after, before, since, until or unless. These words signal that more information is needed.
Put the two together: “We finished the test before the bell rang.” The independent clause is “We finished the test”. The dependent clause is “before the bell rang”.
A quick check for students: read the group of words aloud and ask, “Does this feel finished?” If you are left waiting for more, it is probably a dependent clause.
Common types of phrases
Phrases come in several kinds. For upper elementary and middle school, three are enough to start.
Prepositional phrases
A prepositional phrase begins with a preposition and ends with a noun or pronoun. It tells where, when or how.
- on the shelf
- after lunch
- through the tunnel
- with a blue marker
In the sentence “The books on the shelf are new”, the prepositional phrase “on the shelf” tells which books. The Prepositions and Prepositional Phrases Worksheets packet has 41 pages for grades 4 to 6, with 70 questions in 6 sections, plus a lesson plan and answer key.
Noun phrases
A noun phrase is a noun with the words that describe it: “the tall tree”, “my new notebook”, “a small garden”. It acts as one unit in the sentence.
Verb phrases
A verb phrase is a main verb with its helping verbs: “has been growing”, “will finish”, “did not call”. Students who already know their helping verbs will find these easy to spot.
Subject and predicate: the base of every clause
Every clause has two parts. The subject is who or what the clause is about. The predicate says what the subject does or is, and it includes the verb.
- The science club | built a model volcano. (subject: the science club)
- The bus | stops at the corner. (subject: the bus)
Once students can find the subject and the predicate, they can test whether any group of words is a clause. The Subject and Predicate Worksheets set covers complete, simple and compound subjects and predicates, with an answer key, answer sheet and lesson plan.
Building sentences from clauses
Different clause patterns make different sentence types.
Simple sentence
One independent clause: “The class visited the library.”
Compound sentence
Two independent clauses joined by a comma and a conjunction such as and, but or so: “Sam packed his lunch, and Lena packed her bag.” Each side could stand alone.
Complex sentence
One independent clause and at least one dependent clause. “We stayed inside because it was raining.” Our guide to complex sentence examples goes into this pattern in more depth.
Notice the comma rule. When the dependent clause comes first, a comma follows it: “Because it was raining, we stayed inside.” When it comes second, no comma is needed.
A longer example
Try this one with students: “When the rain stopped, we walked home, and the sun came out.” There are three clauses. “When the rain stopped” is dependent. “We walked home” and “the sun came out” are independent. It is a good challenge for a strong group.
For practice on the comma rules that go with these patterns, the Comma Usage Worksheet Packet has 29 pages for grades 3 to 6, with 40 comma questions across 4 sections, a lesson plan and an answer key.
Sentence fragments and run-ons
Clauses are also the key to two common problems.
Fragments
A fragment is a group of words written as a sentence that is missing something. A dependent clause alone is a common fragment.
- Fragment: “Because the bell rang.”
- Fix: “Because the bell rang, we lined up.”
Run-ons and comma splices
A run-on joins two independent clauses with no punctuation or conjunction. A comma splice joins them with only a comma.
- Run-on: “The bell rang we lined up.”
- Comma splice: “The bell rang, we lined up.”
- Fix with a period: “The bell rang. We lined up.”
- Fix with a conjunction: “The bell rang, and we lined up.”
- Fix with a dependent clause: “When the bell rang, we lined up.”
The Run-On Sentences Worksheets packet has 46 pages for grades 5 to 7, with 70 questions across 6 sections, a lesson plan and an answer key. The Four Types of Sentences Worksheets cover declarative, interrogative, imperative and exclamatory sentences, with an answer key, answer sheet and lesson plan.
Practice ideas for a clauses and phrases worksheet
These activities need only paper and a few sentence examples.
Sort the groups of words
Write groups of words on index cards and ask students to sort them into three piles: phrase, dependent clause and independent clause. A starter set that works: “under the bridge” (phrase), “when the rain stopped” (dependent clause), “the game ended” (independent clause), “running across the field” (phrase), and “while she was reading” (dependent clause).
Cut and combine
Print simple sentences on strips. Students cut and tape two strips together with a conjunction, then add the right comma.
Find and mark
Give a short paragraph. Students underline independent clauses once, dependent clauses twice and circle each prepositional phrase.
Fix the fragment
Give five fragments and ask students to turn them into full sentences by adding an independent clause.
If you want the whole unit in one place, the Punctuation and Sentence Structure Worksheets Bundle has six grammar packets covering how a sentence is built and how it is punctuated, from subjects and predicates to commas, quotation marks and run-ons. It has 254 pages and is 20% off the separate prices.
Sample sentences with answers
Use these as a warm-up. Ask students to label each group of words as a phrase, a dependent clause or an independent clause.
- on the table [phrase: prepositional]
- although it was late [dependent clause]
- the students cleaned the room [independent clause]
- a cold glass of water [phrase: noun phrase]
- if you finish early [dependent clause]
- you may read quietly [independent clause]
Then ask students to build full sentences by pairing a dependent clause with an independent clause. Items 2 and 3 become: “Although it was late, the students cleaned the room.” Items 5 and 6 become: “If you finish early, you may read quietly.” Ask where the comma goes and why.
Commas with clauses and phrases
Comma rules often depend on what kind of group of words comes first. Here are three patterns students can learn.
- After an introductory dependent clause: “When the lesson ended, we packed our bags.”
- After a long introductory phrase: “After the long walk to the park, we sat down to rest.”
- Between two independent clauses with a conjunction: “The test was hard, but everyone finished.”
No comma is needed when the dependent clause comes last: “We packed our bags when the lesson ended.” Students can test their own sentences by moving the clause to the front and back and noting where the comma goes.
A short lesson plan outline
Here is one way to teach the topic across a few lessons.
- Lesson one: subjects and predicates. Students find them in ten short sentences.
- Lesson two: phrase or clause. Students sort index cards into the two groups.
- Lesson three: independent and dependent clauses, with clue words such as because and although.
- Lesson four: simple, compound and complex sentences, with the comma rules.
- Lesson five: fragments and run-ons, with editing practice.
Each lesson can start with a few sample sentences, move to a worksheet section and end with students writing one sentence of their own.
Reading a sentence clause by clause
Take this sentence: “After the game ended, the players shook hands, and the coach thanked the referee.”
- “After the game ended” is a dependent clause. It has a subject, “game”, and a verb, “ended”, but it begins with “after” and cannot stand alone.
- “The players shook hands” is an independent clause.
- “The coach thanked the referee” is an independent clause.
That makes three clauses: one dependent and two independent. The sentence also has a joining word, “and”, with a comma in front of it, because it connects the two independent clauses. Walking through a sentence like this one step at a time shows students that long sentences are built from small, familiar parts.
Ask students to write a sentence of their own with the same pattern: a dependent clause first, then two independent clauses joined by a comma and a conjunction. Trade papers and check each other’s clauses.
Frequently asked questions
Can a phrase have a verb in it?
Yes. “Running across the field” contains the verb form “running”, and “has been growing” is a verb phrase. A phrase is not a clause unless it also has a subject that does the action.
Does every sentence need an independent clause?
Yes. A complete sentence needs at least one independent clause. A dependent clause alone is a fragment.
Is “because” always a clue for a dependent clause?
Almost always. A clause that starts with “because” depends on another clause to finish the idea, so it needs an independent clause with it.
Which grades should learn clauses and phrases?
The packs in this guide are written for a range of upper elementary and middle school grades. The packets name grades 3 to 6, 4 to 6 and 5 to 7, so check each page for the one that suits your group.
