ELA2nd GradeConventions of Standard English
The Standard
Form and use frequently occurring irregular plural nouns (e.g., feet, children, teeth, mice, fish).
Common Core State Standards for English Language Arts
What This Standard Means
Students need to recognize that some plural nouns do not follow the usual add-s pattern. They should be able to say and write common irregular plurals, like one tooth, two teeth, without guessing or overgeneralizing.
Mastery looks like using the correct plural in speech and writing during normal classroom work, not just on a worksheet. Students often get stuck by adding -s to every noun, saying foots or childs, or by memorizing pairs but not using them in sentences.
Ways to Teach It
- Hands-on activity: Sort picture cards labeled one foot, two feet, one mouse, two mice into singular and plural columns.
- Writing prompt: Finish five sentences like, “At the park I saw three ___,” using children, mice, fish, teeth, and feet.
- Quick assessment: Show six singular noun cards and ask students to write the matching plural on mini whiteboards.
- Real-world connection: Read a lunch menu, zoo sign, or class photo caption and circle any irregular plural nouns students find.
