If you look up “irregular” in the dictionary, you’ll find a definition something like this: “not conforming to the usual pattern”. Ok, so how do we teach students something that doesn’t follow the usual grammar patterns (like irregular plural nouns and verbs)? Keep reading for some tips that will make teaching irregular plural nouns and irregular verbs fun and easy in your second grade classroom!

Be sure to read all the way to the end for a list of our other posts in this “Teaching Grammar” blog series – dedicated to making teaching 2nd grade grammar fun and effective at the same time!
What are Irregular Plural Nouns?
Irregular plural nouns are nouns that do not get the traditional “s” ending to become plural. Instead, they may follow a new rule to become plural.
Spelling Rules for Plural Nouns
- When a word ends with an f, change the f to a v and add es. Example: loaf-loaves
- When a word ends with an fe, change the f to v and add an s at then end. Example: life-lives
- If a word ends with an o, add an es to it. Example: potato-potatoes
- Sometimes the vowels change to show a plural. Example: goose-geese
- Some words seem to change completely in their plural form. Example: mouse-mice
- Or, they might not change at all! For example: deer stays deer when plural (so does moose)
AND there are always exceptions to these rules! Wow! That can get confusing! Consider making an anchor chart like the one below for your students to reference.

What are Irregular Verbs?
Students love learning about verbs because it usually involves some movement. And they usually catch on to past tense verbs pretty quickly. But what about irregular verbs? That is, verbs that don’t get the traditional “ed” ending when in past tense.
Examples of Irregular Past Tense Verbs
eat-ate
say-said
buy-bought
Once again, it might be helpful to make an anchor chart similar to the one below for students to reference!

Why teach irregular plurals and verbs?
It might seem like it would be easy to skip these concepts all together when teaching grammar. However, it is important for students to learn these words to become a thorough speaker, reader and writer. They will learn these words through speaking and listening as well as through grammar instruction.
