Instructions

This worksheet helps you understand the two main parts of every complete sentence: the Subject and the Predicate.

  1. The Subject tells you who or what the sentence is about (the 'Hero').
  2. The Predicate tells you what the Subject is doing or being (the 'Action').

Part 1: Finding the Hero (The Subject)

In the sentences below, the Subject is the part that is doing the action.

Directions: Read each sentence. Circle the entire Subject of the sentence (the person, place, or thing the sentence is about).

Example: (My noisy dog) chased a squirrel up a tree.

  1. The bright yellow sun warmed the ground.
  2. My best friend laughed at the funny joke.
  3. A big blue whale swam in the deep ocean.
  4. All the students studied for the math test.
  5. Our school bus drives down Maple Street.

Part 2: Finding the Action (The Predicate)

Now we will focus on the Predicate. The Predicate includes the verb (the action word) and all the words that explain the action.

Directions: Read each sentence. Underline the entire Predicate of the sentence (what the subject is doing).

Example: The speedy race car zoomed around the track.

  1. The friendly baker made delicious cookies.
  2. Dad read a scary book before bedtime.
  3. Tiny raindrops fell quickly from the dark sky.
  4. My sister played soccer outside today.
  5. The sleepy puppy yawned loudly in its bed.

Part 3: Matching Subjects and Predicates

Sometimes sentences get mixed up! Match the Subject column to the correct Predicate column to make five complete, logical sentences. Write the letter of the Predicate in the middle column.

Subject Predicate Letter Predicate
Example: The young artist D A. washes the dinner dishes.
11. The hungry squirrel B. sang a beautiful song.
12. My helpful brother C. landed safely on the moon.
13. The brave astronauts D. drew a picture of the cat.
14. The talented singer E. loves to eat crunchy nuts.
15. That old bicycle F. needs new tires and brakes.

Part 4: Building Complete Sentences

Use the words provided to build new sentences. Remember that every sentence needs both a Subject (who/what) and a Predicate (what they are doing).

Directions: Combine the Subject and Predicate phrases to write one complete, correct sentence on the line.

  1. Subject: (My noisy friends) / Predicate: (chatted all through the movie)
  1. Subject: (A giant iceberg) / Predicate: (floated silently in the icy water)
  1. Subject: (The little ladybug) / Predicate: (crawled across the green leaf)

Challenge Zone (Advanced Thinking)

  1. Take the following simple Subject and make it into a very long and descriptive Predicate (say three or more things about the subject).

Subject: The school principal

Complete Sentence: ___
