Students correct three prefix misapplications — rewrite meaning 'for the first time,' submarine flying above clouds, and misunderstand meaning 'following directions perfectly.' Part B has four fill-in-the-blank questions about re-, pre-, and mis- meanings. Part C has two short-answer questions about the sub- prefix with examples and how re- aids vocabulary decoding.
Correcting prefix misapplications — where students know the definition but apply it incorrectly — targets the exact gap between knowing a rule and using it accurately.

Roots, Prefixes & Suffixes
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The teacher asked us to rewrite our essays, which means to write them for the first time.
Rewrite: The teacher asked us to rewrite our essays, which means to write them again.
2. Fix the sentence:
The submarine flew high above the clouds during the mission.
Rewrite: The submarine traveled deep below the ocean surface during the mission.
3. Fix the sentence:
She misunderstood the directions, so she followed them perfectly.
Rewrite: She misunderstood the directions, so she made several mistakes on the assignment.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The prefix re- means "again," so to rebuild something means to build it again.
2. Adding the prefix pre- to the word "view" creates preview, which means to see beforehand.
3. The prefix mis- means "wrongly," so to mislead someone is to lead them in the wrong direction.
4. A subtitle is a title shown at the bottom of a movie screen, and the prefix sub- means under.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain what the prefix sub- means and give two words that use this prefix. Tell what each word means.
The prefix sub- means "under" or "below." A submarine is a vessel that travels under water. A subway is a train that runs under the ground.
2. How does knowing the meaning of the prefix re- help you figure out unfamiliar words? Give an example.
Knowing that re- means "again" helps me figure out new words. For example, if I see the word "reassemble," I know it means to put something together again.
