Nouns are a person, place, thing, or idea. In 4th grade, you have to become an expert on common and proper nouns. Common nouns name any person, place, thing, or idea.

Examples of singular nouns are boy, church, ox, and butterfly. Examples of plural nouns are boys, churches, oxen, and butterflies. Plural nouns come with rules such as

nouns ending in s,x,ch, sh, or z,- add -es (bushes)
nouns ending in consonant -y- change the y to i and add -es (babies)
nouns ending in vowel -y- just add -s (birthdays)
nouns ending in consonant o- add -es (potatoes)
nouns ending in vowel -o- add -s (zoos)
nouns ending in -f or -fe- change the -f or -fe to -v and add -es (knives)
