Sentence combining worksheets and examples for homeschool

Sentence combining asks your child to join two or three short sentences into one, using a word such as and, because, but, so or when, and to keep every fact. The string snapped. The kite drifted away. becomes When the string snapped, the kite drifted away. Nothing new is added. The child chooses how the ideas connect, and the joining word shows that choice.

Most sentence combining worksheets hand a child pairs of sentences about nothing in particular. This guide takes the sentences from a reading your child already knows, so each choice of joining word is also a check on what the reading says. Below you will find a short original reading, six ways to combine, a worked example, three groups to try with suggested answers, a way to make your own exercises from any book and a free printable worksheet.

What is sentence combining?

Children who are learning to write often produce a row of short sentences that each say one thing. The wind was strong. The kite climbed. It went above the trees. Every sentence is correct. Read together, they sound like a list, and the reader has to guess how the ideas relate. Sentence combining teaches the child to make that relation visible: the kite climbed because the wind was strong, and it climbed above the trees.

It is one of the better-studied ways to teach writing. Writing Next, a 2007 report for Carnegie Corporation of New York by Steve Graham and Dolores Perin, reviewed the research on writing instruction for older pupils in schools. Most of the studies it found compared sentence combining with more traditional grammar lessons. The effects were consistently positive and moderate, with an average effect size of 0.50. Those studies were not about younger children working at home, so read that as a reason to take the activity seriously, not as a promise about any one child.

The Writing Revolution also lists sentence combining among its strategies (checked 23 October 2026). Both sources are written for classrooms. What follows is our own version for a parent and one child at the table.

Read this short passage together

Before any writing, ask what happened to the kite and who helped. Leave the passage in view. Every combined sentence your child writes should still be true to it.

Six ways to combine sentences

Each way of combining makes a different connection between the ideas. The table shows the six we use most, each with a pair of short sentences taken from the reading and one way to join them.

A seventh move is smaller and comes up all the time: folding a describing word into the other sentence. The kite was red. The kite landed in a tree. becomes The red kite landed in a tree. Children often do this on their own once they hear how clumsy the repeated noun sounds.

Notice that because and so carry the same pair of ideas in opposite directions. The kite climbed because the wind was strong and The wind was strong, so the kite climbed say the same thing. A child who can turn one into the other has understood which idea is the cause.

A worked example: three sentences become one

Write three short sentences from the reading on the page:

Now combine them while you think aloud: “The first sentence happened before the others, so it can go at the front with when. The second and third are both about the kite, so and can join them without saying it again. I need to keep the sheep and the tall oak. Those are facts, and combining is not allowed to lose them.”

Read it aloud together and ask your child to find each of the three original sentences inside it. Then check the facts one by one against the passage: the string, the field, the sheep, the oak. If one is missing, the sentence is shorter but it is not finished.

There is more than one good answer. After the string snapped, the kite drifted over a field of sheep. It landed in a tall oak tree. combines only two of the three, and that is fine too. Ask which version is easier to follow when read aloud. Usually the answer is the one where the reader never has to stop and work out what it means.

Let your child try three groups

Use the same passage. Each group names the way to combine. Say the sentence aloud before writing it if your child needs a start. One group is plenty for a day.

1. Use because: Maya thanked Mr Hale. He had lifted the kite down without tearing it.
2. Use an appositive: Maya's grandfather had built the kite himself. He could not climb the oak tree.
3. Use although: The kite was stuck high in the oak. Mr Hale lifted it down without tearing it.

The third group is the hardest, because although asks your child to hold two ideas that seem to pull against each other. If it is too much today, let them try it with but first: The kite was stuck high in the oak, but Mr Hale lifted it down without tearing it. Then show how although moves the contrast to the front.

When a combined sentence goes wrong

Most problems fall into five kinds, and each has a quick response.

• A fact goes missing. When the string snapped, the kite landed in a tree. The field and the oak have gone. Put the original sentences next to the new one and tick off each fact.
• The joining word changes the meaning. Grandfather's knee was sore because he could not climb the tree. The cause and the result have swapped. Ask which happened first and which happened because of it, then check the passage.
• Everything is joined with and. The wind was strong and the kite climbed and the string snapped and it landed in a tree. Nothing is wrong, but nothing is connected either. Ask how the strong wind and the climbing kite are related, and offer so.
• Two sentences are joined with a comma. The string snapped, the kite drifted away. That is a run-on sentence. A comma on its own cannot join two sentences. Add a joining word, or keep two sentences.
• The sentence gets too long to follow. Combining four or five sentences into one rarely helps. If your child runs out of breath reading it aloud, split it back into two.

Choose one of these to work on in a sitting. Correcting everything at once turns a short activity into a long one.

Make your own exercises from any book

The best source of practice is the book your child is already reading. Choose a long, clear sentence the author wrote and split it into short sentences on a card. Your child combines them, then you both compare their version with the author's.

The author's sentence works as an answer key you did not have to write. Your child's version does not need to match it. Often the comparison is the best part: the author put the time at the front and your child put it at the end, or the author used while where your child used and. Ask which one sounds better to them and why. A child who says “theirs tells you the important part first” has noticed something about writing that is hard to teach directly.

Pick sentences with two or three ideas, not six, and stay with the ways your child has practised. If the book's sentence uses a joining word you have not taught yet, that is a good place to start the next lesson.

Combining or expansion: which comes first?

The two are often taught together, and many worksheets put them on the same page. They move in different directions. Sentence expansion starts from a bare kernel and adds new details by asking when, where and why. Combining starts with the details already written, spread over several short sentences, and asks how they fit together.

For most children, expansion is easier to begin with, because the questions tell them what to add. Combining asks for a judgement about how ideas relate, and the joining words carry that judgement. If because, but and so are still new, spend a few days on because, but and so first. Those three words are the heart of most combining.

A free printable sentence combining worksheet

If you would like practice on paper, our Sentence Craft sample is a complete 11-page worksheet PDF you can print. It is built on one public-domain reading, Down the Rabbit-Hole by Lewis Carroll, which is also free as a reading PDF. Read the chapter together first.

Section 11, Sentence combining, is the exercise in this guide. Its directions ask your child to combine each group of statements in the named way and keep every fact. It opens with a worked example, Because Alice saw the Rabbit take out a watch, she became curious., then gives three groups: one to join with because, one with so and one with an appositive about the White Rabbit.

The other ten sections practise the moves that lead up to it: fragments and sentences, word order, run-on sentences, adding useful information, asking questions, because, but and so, four sentence types, subordinating conjunctions, transitions and appositives. This sample is the Guided Practice answer copy, so each exercise shows a suggested answer. Read it with your child and talk about the answers, or copy the exercises into a notebook and compare afterwards. One section is enough for a day. You may print and adapt the samples for your own household.

Where combining fits with paragraph writing

Combining is where sentence practice starts to sound like real writing. A child who can join two ideas with the right word is ready to write several sentences that answer one question and put them in order as a paragraph. If you are new to this way of teaching, our guide to starting The Writing Revolution at home shows where each sentence activity fits.

You can also open the other free samples on our home page. There is one for each of our six kinds of writing practice.
