4th grade subject and predicate worksheets

Tap to see another sample sheet.

Fourth grade worksheets use longer, more natural sentences where the subject carries phrases (the boy in the striped shirt) and the predicate stacks details. Underlining the complete subject at this level is the setup skill for clauses and complex sentences.

The kind of sentences you'll get

Underline the complete subject of each sentence.

  1. The owls in the hollow oak wake at dusk.

    Answer: The owls in the hollow oak

  2. The bikes outside the gym tipped over in the wind.
  3. The firefighters at Station Nine wash their truck on Fridays.

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 4th grade sheet

4th grade sheets draw from 60 sentences, 12 to a page. All 60 are on 3rd grade sheets too, along with 60 more.

Some of the words to find:

The library books on my deskher brotherThe horses in the far pastureThe trail behind the ranger stationThe planets in the mobileThe younger kids at the bus stopThe clerk at the corner marketThe vines along the back fenceThe heron at the edge of the pondMy cousins from the city

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

How to teach this

The trap at this grade is a phrase inside the subject: in 'The girl with the green backpack waved,' the whole phrase before waved is the subject. Have your child find the verb, then read everything before it as one chunk. If the sheet goes well, flip the task: you name a predicate, they invent a subject for it.

Watch for: Kids underline only one word. The COMPLETE subject takes all its describing words along: not hen but the little red hen. Kids split at the middle of the sentence by eye. The real split is right before the verb; finding the verb first makes the subject fall out on its own.

Common questions about 4th grade subject and predicate

How do the fourth grade sentences differ?
The subjects carry phrases: 'the boy in the striped shirt.' Your child has to keep the whole phrase inside the underline, which is exactly the chunking skill that clauses and complex sentences need next.
What should we practice after this?
Combining sentences and run-on sentences. Both lean on spotting where a subject-predicate pair begins and ends, so this page is the foundation for that editing work.
