Subjects and predicates

Subjects and predicates worksheet for 3rd grade: students underline the complete subject and circle the complete predicate in each sentence. Part of our subjects and predicates sentences collection. Aligned to Common Core standards.

How do I use this worksheet?

Introduce the skill with a brief whole-class activity, such as calling out examples and asking students to give a thumbs up when they hear subjects and predicates in a sentence. Then let students work through the worksheet independently or in pairs, referring to a class anchor chart if one is available. When reviewing answers, ask students to explain why an answer is correct rather than just confirming it. These subjects and predicates worksheets work well as a focused practice activity, a homework assignment, or a warm-up at the start of a language arts lesson.

What students will practice

  • Students will identify and correctly use subjects and predicates in sentences and short passages.
  • Students will distinguish subjects and predicates from related language concepts and apply rules consistently.
  • Students will demonstrate understanding of subjects and predicates in both reading and their own writing.

What does this worksheet teach?

These subjects and predicates worksheets for 3rd grade give students the targeted language arts practice they need to master this important grammar skill. Students identify, sort, complete, and write using subjects and predicates through a variety of exercises designed to reinforce both recognition and application. Our sentences worksheets connect grammar practice to reading and writing so students see how subjects and predicates works in real language. Building a solid understanding of subjects and predicates in 3rd grade sets students up for stronger writing and clearer communication in every subject.

What grade level is this subjects and predicates worksheet for?

"Subjects and predicates" is written for 3rd Grade (Ages 8-9), and it covers Common Core L.3.1.I. If your little one is a year younger but already steady on sentences, the page still works. You may just need to read the instructions out loud. And if they are older and subjects and predicates never quite stuck, this is a short review rather than busywork.

Can I use this subjects and predicates worksheet for homeschool or classroom?

Yes, both. We made it for 3rd Grade sentences, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with subjects and predicates. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

What is the difference between a subject and a predicate?

The subject is the noun or noun phrase that the sentence is about (e.g., 'The brown dog'), while the predicate includes the verb and everything that follows it (e.g., 'ran across the yard').

How does knowing subjects and predicates help 3rd grade writers?

Understanding sentence structure helps students write complete, clear sentences and avoid run-ons or fragments - knowing that every sentence needs both a subject and a predicate gives writers a built-in self-check.

What activities are used to teach subjects and predicates in 3rd grade?

Students typically underline the subject once and the predicate twice in given sentences, match sentence halves (subjects to predicates), and write their own sentences identifying each part.

Three kids at home and these work for all of them. Easy to adapt up or down a grade level depending on the day.

We've tried a lot of printable worksheets but these are consistently the best quality. My son asks to do them.

I print a stack Monday morning and I'm set for the week. My sub folder is entirely ClassWeekly at this point.

I use these in intervention groups. One skill per page means I can see exactly where a student is getting stuck.
