Recap: Regular Plurals
When there is more than one of a noun, the noun becomes a plural. We make regular plurals by adding 's' or 'es' to the end of singular nouns. Let's look at a few examples of regular plurals...

Girl → girls

Boy → boys

Dog → dogs

Pig → pigs
Using Apostrophes with Regular Plural Nouns
We sometimes need to show possession in a sentence, which is when something belongs to someone or something. We do this using an apostrophe ('). Let's walk through an example of how you add an apostrophe to a regular plural noun...

1) Make a sentence using possession
- The birds cage was very small.
- 'Birds' is a regular plural. The plural form 'birds' is the singular 'bird' + 's'.
- There is possession in the sentence because the cage belongs to the birds.

2) Put an apostrophe after the 's'
- The birds' cage was very small.
