Instructions

Welcome to The Sentence Repair Shop! A complete sentence needs five things to work properly:

  1. Starts with a Capital Letter.
  2. Uses clear Spacing between words.
  3. Ends with Punctuation (like . ? or !).
  4. Has a Subject (Who or What is doing the action).
  5. Has a Predicate (The action or what the Subject is doing).

Complete the following tasks to practice building and fixing sentences.

Section 1: Fixing the Flow (Capitalization, Spacing, Punctuation)

Read each sentence below. Check the boxes if the sentence follows the three basic rules. If it needs fixing, rewrite the sentence correctly in the space provided.

Sentence needing repair Capital Letter? Proper Spacing? Ending Punctuation? Corrected Sentence

1. i love pizza and apples
2. Mom bought new shoes today.
3. thebirdfliewa
4. what is your favorite color

Section 2: Subject and Predicate Identification

The Subject tells you who or what the sentence is about (Nouns/Pronouns). The Predicate tells you what the subject is doing (Verbs/Actions).

In the table below, circle the Subject and underline the Predicate in each sentence. Use the example to guide you.

Sentence Circle the Subject / Underline the Predicate
Example: My little sister built a sandcastle. Circle: sister. Underline: built a sandcastle.
1. The bright moon shines high in the sky.
2. The brave firefighter saved the cat.
3. My neighbor's car broke down yesterday.
4. We will eat dinner at six o’clock.
