4th grade combining sentences worksheets

Fourth grade sentence combining turns productive: the two short sentences print above a writing line, and your child writes the combined sentence, weighing a comma plus joining word against a clause starting with because, when, or although. The answer key shows the strongest combination, and a choice version is one click away.

The kind of sentences you'll fix

Read the two sentences. Write one sentence that combines them. Use a joining word.

  1. The storm knocked out the power. The class kept working by the windows.

    Fixed: Although the storm knocked out the power, the class kept working by the windows.

  2. The bakery ran out of rye. The deli sent over two loaves.
  3. The ferry docked at noon. The market opened its stalls.

Every print pulls a fresh set of sentences at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

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

How to teach this

Two good tools now compete: comma plus conjunction, or a clause starting with because, when, or although. Have your child say both versions out loud and pick the one that keeps the emphasis where the original pair put it. Talking through one item well beats rushing five.

Watch for: Kids glue sentences with just a comma: 'Ben has a kite, Ben has a drum.' That is a comma splice. Joining needs a joining word, or the repeats folded away. Kids pick and for everything. And adds, but pushes back, or offers a choice, so gives a result. Reading the combined sentence aloud with the wrong word usually exposes it.

Common questions about combining sentences

What is new in fourth grade?
Two things: your child now writes the combination instead of circling one, and subordinating words (because, when, after, although) join the toolbox beside and, but, and so.
How do I grade a written answer?
Compare it to the key's model sentence. If your child's version keeps every idea, says nothing twice, and joins the parts legally, it counts, even when the joining word differs from the model.
