Sentence Combining

Combining sentences encourages students to take two or more short, choppy sentences and combine them into one effective sentence — to make their writing more readable and engaging. Sentence combining is a skill that develops over several short practice sessions.

What is sentence combining?

We’ve all read pieces of student writing that go something like: “I walked to the park. I went down the slide. I played on the swing. I heard the ice cream truck. I ran to get in line …” Inexperienced authors tend to write a series of short, choppy sentences that follow a similar — or even identical — sentence structure. 

Sentence combining is a technique for “smoothing out” choppy writing by varying sentence structure and making a piece of writing more engaging for the reader. In the “I went to the park” example, simply joining pairs of sentences by adding a conjunction (“I went down the slide and played on the swing. I heard the ice cream truck and ran to get in line.”) makes the piece more readable. Over time, students can progress from joining two short sentences to more sophisticated sentence combining strategies.

Why teach sentence combining?

  • It helps students make their writing more readable and engaging.
  • It creates opportunities to teach grammar and punctuation in a meaningful context.
  • It shows students how and why to revise their writing.
  • The process encourages interesting word choices and transition words.

How to teach sentence combining

Experienced writers know when to combine choppy sentences — and break up run-on sentences, too — without giving it much thought. Beginning writers, on the other hand, need to be explicitly taught. Since the most straightforward way to combine sentences is to merge two simple sentences into a compound sentence using a connector word, that’s a good place to begin instruction.

Once students are comfortable using connector words to combine sentences, they can be introduced to more sophisticated types of sentence combining, like pulling key words and concepts from an otherwise unnecessary sentence and embedding them in a base sentence.

Teacher modeling, discussion, and guided practice will help students internalize these strategies and begin to use them in revising their own writing and providing constructive feedback to other writers. 

Below is a sampling of different kinds of sentence combining, including examples:

Producing compound sentences using conjunctions (e.g.: and, but)

Example:
The weather was perfect.
The girls were playing soccer.
The weather was perfect, and the girls were playing soccer.

See “conjunction ... junction” example 

Producing compound subjects and objects

Example:
The book was good.
The movie was good.
The book and the movie were good.

Inserting adjectives and adverbs

Example:
The girl drank lemonade.
The girl was thirsty.
The thirsty girl drank lemonade.

After several modeled and shared lessons, encourage students to combine sentences as a part of revising their own writing. Give students an opportunity to share sentences they combined. Discuss ways the revision improved the quality of the writing.

Watch a classroom example: using pronouns and conjunctions to combine sentences (grade 2, whole-class)

The teacher guides students through combining and revising a series of sentence pairs using techniques such as inserting connector words and substituting pronouns for nouns that appear more than once. Watch video

Differentiate instruction

  • Begin sentence combining lessons with oral practice. If writing is challenging for some students, intentionally pair them with strong writers for cooperative work so they have peer support as they transition from speaking to writing their sentences.
  • Make sure students have the vocabulary and background knowledge they need to understand the sentences that will be combined.
  • Use sentences from familiar books and stories for modeling and practice.
  • Provide extra support by underlining critical words in the sentences being combined. For example, “The cake was delicious. The cake was chocolate.”
  • Vary the number and complexity of sentences being combined depending on students’ ability and experience with the strategy.

See the research that supports this strategy

Some of the research done that involves sentence combining comes from a whole language perspective. We”ve listed some of that research here. Our instructions for using sentence combining encourage a more explicit approach to using the strategy than what is included in some of the research listed below.

Children's books to use with this strategy

The Red Book

The Red Book

By: Barbara Lehman
Genre: Fiction, Fantasy
Age Level: 3-6
Reading Level: Beginning Reader

A girl finds a book with a red cover on a winter day that transports her to a sunny beach. The idea of getting lost in a book (figuratively and magically) is presented wordlessly; only illustrations are used. The story can be told or written any number of ways according to the writer's interpretation of the story.

One Boy

One Boy

By: Laura Vaccaro Seeger
Age Level: 3-6
Reading Level: Beginning Reader

This concept book uses die-cuts to highlight words within words that are actually short sentences (e.g., turn the page and "one boy" becomes "all alone"). Try to combine sentences to create a series of sentences or build them into one story. (The last illustration pulls the apparently disparate vignettes into one.).

Art and Max

Art and Max

By: David Wiesner
Genre: Fiction
Age Level: 6-9
Reading Level: Independent Reader

The unexpected occurs when two lizards — one an accomplished artist, the other a beginner — begin painting. Fast-paced and often funny, the two voices of the characters are as distinct as their individual creative process. This ingenious book works on several levels.

Say Hello

Say Hello

By: Rachel Isadora
Genre: Fiction
Age Level: 0-3
Reading Level: Pre-Reader

Mama, Carmelita, and their dog Manny greet people in their diverse neighborhood as they walk to see Abuela Rosa. Everyone says "hello" but in their own language — ranging from Italian and French to Hebrew and Arabic to slang American greetings. It is Manny's "woof," however, that is universal. Textured illustrations make Carmelita’s community familiar and accessible.

Love the information. I plan on using this in my classroom on Monday! I can't wait to stretch my third graders!

i was wondering how we can turn 3 sentences into a compound sentence? is that possible?

These are excellent ideas for sentence combining. I plan to use them with my beginning writers.
Thank,
