What This Standard Means
What Students Need to Do
- Students change a noun that names one item into a noun that names more than one. They say forms such as cats and buses clearly in phrases and sentences.
What Mastery Looks Like
- Given pictures of one item and several items, a student quickly says both forms without a model. The student uses the correct plural form in a short sentence, such as “I see three buses.”
Common Misconceptions
- Some students add an extra syllable where it does not belong, saying “catses,” or leave the noun unchanged after “two.” Others say “brush-s” instead of “brushes.”
How to Assess It
- Show pictures of one cat, three cats, one bus, and two buses. Ask the student to name each picture and use each plural in a sentence.

Ways to Teach It
Give pairs of toy animals and objects to students, then have them hold up one or several and say each noun form aloud.
Show one box and three boxes, then ask, “What changed in the word when the number changed?”
Play Plural Toss by tossing a beanbag, naming one object, and having the catcher say the plural before tossing again.
Take a classroom walk and have students name single items and groups, such as chair and chairs or box and boxes.
