Capitalization & Punctuation — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which sentence uses correct capitalization?
A) i went to the store.
B) I went to the Store.
C) I went to the store.
D) i Went to the store.
This sentence begins with a capital I (the word I is always capitalized) and ends with a period, so the capitalization and punctuation are both correct.
2. Which word should always be capitalized?
A) running
B) happy
C) tuesday
D) under
Tuesday is a day of the week, which is a proper noun. It should always be written with a capital T, no matter where it appears in a sentence.
3. What goes at the end of Where is my backpack?
A) period
B) exclamation point
C) comma
D) question mark
"Where is my backpack" starts with the word Where and is asking something, so the correct ending punctuation is a question mark.
4. Which sentence is written correctly?
A) she lives in texas.
B) She lives in Texas.
C) She lives in texas.
D) she Lives in Texas.
She starts the sentence with a capital letter, Texas is a state and also capitalized, and the sentence ends with a period — every rule is followed.
Part B: Fill in the Blank
Write the correct answer on each line.
1. Washington is the capital of our country.
Washington is the name of the capital city of the United States. City names are proper nouns, so the W must be capitalized.
2. My sister was born in June.
June is a month of the year, which is a proper noun, so it always starts with a capital J.
3. How old are you?
The sentence starts with the question word How, so you know it is asking something. Asking sentences end with a question mark.
4. I can not believe we won!
Winning something surprising calls for strong feeling, so this excited sentence ends with an exclamation point.
5. On Thursday, we go to the library.
Thursday is a day of the week and therefore a proper noun. It begins with a capital T every time it is written.
