This Grade 3 English grammar worksheet focuses on Irregular Plural Nouns (advanced list) and helps learners move beyond basic -s and -es plural rules. Designed for young learners, this worksheet strengthens grammatical accuracy by teaching plural forms that change spelling completely, stay the same, or follow special patterns.
Students practice identifying and using irregular plural nouns such as children, mice, geese, oxen, teeth, deer, and people through a variety of engaging, age-appropriate activities. The worksheet includes multiple-choice questions, fill-in-the-blanks, picture-based matching, underlining tasks, and passage-based paragraph completion. Each exercise encourages learners to observe sentence context carefully and apply the correct plural form with confidence.
Irregular plural nouns help Grade 3 students understand that English does not always follow fixed spelling rules. Learning this topic is important because:
1. Some nouns change completely in plural form (man → men, mouse → mice).
2. Some nouns remain the same in singular and plural (deer, fish, sheep).
3. These forms are commonly used in reading, writing, and spoken English.
4. Mastery of irregular plurals improves sentence accuracy and fluency.
