Title: Child to Children, Mouse to Mice: Grade 6 English Grammar Worksheet on Irregular Plural Nouns
Have you ever wondered why we say “children” instead of “childs,” or “mice” instead of “mouses”? That is because these are irregular plural nouns. In Grade 6, learning about irregular plural nouns helps you understand that not all nouns follow the simple rule of adding “s” or “es” to make them plural. Some nouns change completely. For example, the plural of child is children, not “childs.” The plural of mouse is mice, not “mouses.” The plural of foot is feet, not “foots.” The plural of tooth is teeth, not “tooths.” This Grade 6 English grammar worksheet on irregular plural nouns will teach you the most common irregular plurals, help you avoid mistakes, and improve your writing and speaking accuracy.

Why Is It Important to Learn This?
Learning about irregular plural nouns is important for several reasons. First, not all nouns follow the simple rule of adding “s” or “es.” The plural of child is children, not “childs.” Using “childs” is a common mistake. Second, the plural of mouse is mice, not “mouses.” Saying “mouses” sounds incorrect to native speakers. Third, the plural of tooth is teeth, not “tooths.” Fourth, the plural of foot is feet, not “foots.” Fifth, this topic is tested in grammar exams where you may be asked to choose the correct plural form or correct errors. Finally, using correct irregular plurals makes your English sound more natural and educated.

Where Will This Knowledge Help You?
Knowledge of irregular plural nouns will help you in many academic and real-life situations:
1. Grammar exams and language tests – Many questions ask you to choose the correct plural form. This worksheet directly prepares you for those questions. You will know that “children” is correct, not “childs.”
2. Writing essays and stories – Using correct plurals makes your writing look professional. “The women went to the market” is correct. “The womans went to the market” is incorrect.
3. Speaking English fluently – Native speakers use irregular plurals naturally. Saying “mice” instead of “mouses” will make you sound more fluent.
4. Reading comprehension – Recognizing irregular plurals helps you understand what you read. If you see “mice,” you know it means more than one mouse.
5. Avoiding common errors – Many English learners say “childs,” “mouses,” “foots,” “tooths,” “womans,” and “mans.” Learning the correct forms helps you avoid these mistakes.
6. Building a strong grammar foundation – Irregular plurals are basic but essential. Mastering them is a key step toward advanced English skills.

4. “Foots” is always wrong – Never write “foots.” The correct plural is feet.
5. “Tooths” is always wrong – Never write “tooths.” The correct plural is teeth.
6. “Womans” is always wrong – Never write “womans.” The correct plural is women.

8. “Leafs” is wrong for tree leaves – The correct plural of leaf (from a tree) is leaves. “Leafs” is only used for the Toronto Maple Leafs hockey team.
9. “Wolfs” is wrong – The correct plural of wolf is wolves. Change the “f” to “ves.”
10. What examiners expect – Examiners expect you to know the correct irregular plural forms. They expect you to correct errors like “childs” to “children,” “mouses” to “mice,” “foots” to “feet,” “tooths” to “teeth,” “womans” to “women,” “mans” to “men,” “peoples” to “people” (when referring to multiple individuals), “leafs” to “leaves,” and “wolfs” to “wolves.”
11. How to score full marks – When answering multiple-choice questions, choose the form you know is correct. If you are unsure, remember the most common irregulars. For true and false, know that mouse does NOT become mouses, child does NOT become childs, man does NOT become mans, baby does NOT become babys, and leaf does NOT become leafs.
12. For underlining tasks (Exercise No. 4) – Read each sentence. Look for plural nouns. If the plural form is incorrect (like “womans,” “mouses,” “childs,” “foots,” “peoples,” “leafs,” “wolfs”), underline it and write the correct form.
13. For paragraph correction (Exercise No. 5) – Read the paragraph slowly. Look for every plural noun. Check if it is correct. Correct “womans” to “women,” “childs” to “children,” “foots” to “feet,” “mouses” to “mice.” “Leaves” and “babies” and “people” are already correct.
