Hey proper people! When you learned to write your name, you probably learned to start it with a capital letter. Do you know why? Because you are a proper noun! In this lesson, students learn all about proper nouns. A proper noun is the specific name of a person, place, or thing. Just like your name is capitalized, as is the name of your city or favorite cereal, all proper nouns must begin with a capital letter. And so is my friend, the MightyOwl!
