Teacher’s Guide

Common Misconceptions:

  • Students may try to add -s or -es to all nouns, including irregular plurals.
  • They may confuse singular and plural forms, especially when the words sound similar.

Scaffolding Ideas:

For Struggling Students:

  • Use fewer irregular plural nouns at a time and focus on one or two examples.
  • Incorporate more visual aids and physical objects to represent singular and plural forms.
  • Allow extra practice with oral repetition before writing.
For Advanced Students:

  • Introduce less common irregular plural nouns (e.g., feet, geese, criteria).
  • Encourage the student to write short paragraphs using multiple irregular plural nouns.
  • Have the student explore the origin of some irregular plural nouns for deeper understanding.

Pacing Recommendations:

  • Spend about 10-15 minutes on introduction and examples.
  • Use 15 minutes for hands-on sorting and practice activities.
  • Reserve the last 15 minutes for sentence writing and review.

Standards

  • 3.L.1f — Demonstrate command of the conventions of standard English grammar and usage when writing or speaking; specifically, form and use irregular plural nouns.
