Standard: Demonstrate command of the conventions of standard English grammar and usage when writing or speaking, including phrases and clauses, sentence variety, and misplaced/dangling modifiers.

What to Do

  1. Phase 1 — Identify: Read each sentence. Bubble in the option that names the error (or "No Error").
  2. Phase 2 — Fix: Read the original sentence and the instruction. Rewrite it correctly on the lines below.
  3. Use the checklist at the end to review your work.

Assignment Overview

Time for GRAMMAR POWER PRACTICE. You'll move misplaced modifiers, anchor dangling ones, comma coordinate adjectives correctly, and combine choppy sentences for sharper meaning.

Phase 1: Identify the Error
1
The student read a book about black holes sitting in the cafeteria.
  1. Dangling Modifier
  2. Misplaced Modifier ✓ Correct
  3. Coordinate Adjective Error
  4. No Error
Why: The phrase 'sitting in the cafeteria' is placed next to 'black holes,' making it sound like the black holes were sitting in the cafeteria! It should be closer to 'student': 'Sitting in the cafeteria, the student read a book about black holes.'
2
She served sandwiches to her friends on paper plates.
  1. Misplaced Modifier ✓ Correct
  2. No Error
  3. Sentence Structure Error
  4. Dangling Modifier
Why: The phrase 'on paper plates' is next to 'friends,' making it sound like the friends are on paper plates! It should be: 'She served sandwiches on paper plates to her friends.'
3
The teacher only gave extra credit to students who stayed after school.
  1. Coordinate Adjective Error
  2. Sentence Structure Error
  3. Misplaced Modifier ✓ Correct
  4. No Error
Why: The word 'only' is misplaced. As written, it suggests the teacher did nothing else but give extra credit. It should be: 'The teacher gave extra credit only to students who stayed after school.'
4
After finishing the experiment, the lab report was easy to write.
  1. Misplaced Modifier
  2. No Error
  3. Dangling Modifier ✓ Correct
  4. Sentence Structure Error
Why: Who finished the experiment? The sentence says 'the lab report' finished it, which makes no sense. A person finished the experiment, but that person is missing from the sentence.
5
Covered in mud from practice, the white carpet was ruined when Marcus walked inside.
  1. Coordinate Adjective Error
  2. Dangling Modifier ✓ Correct
  3. Misplaced Modifier
  4. No Error
Why: The phrase 'covered in mud from practice' dangles because it's placed next to 'the white carpet,' but the carpet wasn't at practice. Marcus was covered in mud, so the sentence should start with him as the subject.
6
While scrolling through social media, the homework deadline passed without notice.
  1. No Error
  2. Misplaced Modifier
  3. Sentence Structure Error
  4. Dangling Modifier ✓ Correct
Why: The homework deadline wasn't scrolling through social media — someone was! The modifier dangles because the actual person doing the scrolling is never mentioned as the subject.
7
The dedicated talented athletes trained every day after school.
  1. Misplaced Modifier
  2. No Error
  3. Coordinate Adjective Error ✓ Correct
  4. Dangling Modifier
Why: 'Dedicated' and 'talented' are coordinate adjectives — you could say 'dedicated and talented' or swap them to 'talented, dedicated.' They need a comma: 'The dedicated, talented athletes trained every day.'
8
We watched a suspenseful gripping documentary about ocean exploration.
  1. Sentence Structure Error
  2. Coordinate Adjective Error ✓ Correct
  3. No Error
  4. Misplaced Modifier
Why: 'Suspenseful' and 'gripping' are coordinate adjectives — you could say 'suspenseful and gripping' or reverse them. They need a comma: 'a suspenseful, gripping documentary.'
9
She wore a colorful bright scarf to the school spirit rally.
  1. Dangling Modifier
  2. No Error
  3. Misplaced Modifier
  4. Coordinate Adjective Error ✓ Correct
Why: 'Colorful' and 'bright' are coordinate adjectives — you could say 'colorful and bright' or 'bright, colorful.' They need a comma: 'a colorful, bright scarf.'
10
The volcano erupted violently. Ash covered the entire valley.
  1. Coordinate Adjective Error
  2. Misplaced Modifier
  3. Sentence Structure Error ✓ Correct
  4. No Error
Why: These two ideas are closely related — the ash covering the valley is a result of the eruption. A complex sentence would show this cause-and-effect relationship better: 'When the volcano erupted violently, ash covered the entire valley.'
11
She wanted to try out for the play. She was nervous about performing in front of people.
  1. No Error
  2. Sentence Structure Error ✓ Correct
  3. Dangling Modifier
  4. Coordinate Adjective Error
Why: These ideas contrast with each other — she wanted to try out BUT was nervous. A compound or complex sentence would show this tension: 'She wanted to try out for the play, but she was nervous about performing in front of people.'
12
The internet went down at school. Students had to use printed textbooks instead.
  1. Misplaced Modifier
  2. Dangling Modifier
  3. No Error
  4. Sentence Structure Error ✓ Correct
Why: The second event is a direct result of the first. A complex sentence would show this cause-and-effect clearly: 'When the internet went down at school, students had to use printed textbooks instead.'
13
After studying for three hours, Maria felt confident about the history test.
  1. Dangling Modifier
  2. No Error ✓ Correct
  3. Misplaced Modifier
  4. Sentence Structure Error
Why: This sentence is correct! The modifier 'after studying for three hours' properly connects to 'Maria,' who is the one who studied.
14
The experienced, knowledgeable tutor helped students prepare for the state exam.
  1. Coordinate Adjective Error
  2. Misplaced Modifier
  3. No Error ✓ Correct
  4. Dangling Modifier
Why: This sentence is correct! 'Experienced' and 'knowledgeable' are coordinate adjectives, and they are properly separated by a comma.
15
Although the game was tied in the fourth quarter, our team pulled ahead with a three-point shot.
  1. Sentence Structure Error
  2. No Error ✓ Correct
  3. Coordinate Adjective Error
  4. Misplaced Modifier
Why: This sentence is correct! It uses a complex sentence structure with 'although' to show the contrast between the tied game and the team pulling ahead.
16
She wore a beautiful red dress to the school dance.
  1. No Error ✓ Correct
  2. Coordinate Adjective Error
  3. Dangling Modifier
  4. Misplaced Modifier
Why: This sentence is correct! 'Beautiful' and 'red' are NOT coordinate adjectives — you wouldn't say 'red beautiful dress,' and 'beautiful and red dress' sounds awkward. No comma is needed.
Phase 2: Fix the Sentence

4
Dangling Modifier

7
Coordinate Adjective Error
The enthusiastic supportive crowd cheered for every player on the team.
