Most plural words end with an "s" or "es", but irregular plural nouns like to break the rules! Instead of adding "s" at the end, these special words completely change their spelling when there is more than one. For example, one child becomes two children, and one mouse becomes a group of mice. Practicing these special words helps make your writing super strong!

Supporting 3rd grade Grammar Success
By the third grade, students are already familiar with basic plural rules, but irregular plural nouns often need a quick review. Because these words do not follow the standard rule of adding '-s' or '-es', they require memorization and regular practice. Mastering these tricky forms builds spelling confidence and prepares students for more advanced writing.
