Usually when you see a chart with irregular verbs, it only contains the different forms of the irregular verbs. Sometimes that is not enough information to really understand these verbs because they don't follow all the grammar rules.
This article discusses what makes a verb irregular and how to change them from singular to plural.

For plural nouns and pronouns,
Sometimes you add an "es," like with catch and catches, go and goes, do and does, and teach and teaches. Other times you have to change a "y" to an "i" and then add an "es," like with fly and flies.
