Capitalization & Punctuation — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. My dog name is Buddy.
Buddy is the dog's name, and names of pets are proper nouns that always begin with a capital letter.
2. Is it time to go home?
The sentence begins with "Is it," which signals a question. Questions end with a question mark (?).
3. We went to Denver on Saturday.
Denver is the name of a specific city in Colorado, so its D must be capitalized just like all city names.
4. She ran all the way to school.
She is the first word of the sentence, so the S must be capitalized to show where the sentence starts.
5. Look out for that car!
"Look out!" is a warning that shows urgency and strong feeling, so the sentence ends with an exclamation point.
6. I was born in September.
September is the ninth month of the year, and all month names are proper nouns that begin with a capital letter.
7. The sun is very hot today.
Hot describes how the sun feels on a warm day. It is a regular describing word, not a name, so it stays lowercase.
8. Can Anna come to my party?
Anna is a person's name, which is a proper noun. People's names always start with a capital letter.
9. Today is Wednesday, and we have gym class.
Wednesday is a day of the week, which is a proper noun, so it begins with a capital W.
