This Grade 2 worksheet introduces irregular plurals through multiple-choice and fill-in-the-blank questions. Students choose between tricky options for words like foot, child, mouse, and tooth. Four multiple-choice items and five fill-in-the-blank prompts help Grade 2 learners memorize plurals that break the rules. Hints guide thinking, and detailed reasons explain each answer so young writers remember feet, children, mice, and teeth during independent writing time.
