Welcome to the world of plural nouns! In this worksheet, you'll get to play with words and decide how to convert them into their plural forms. We've got two big boxes for you - one for words that become plural by adding a simple 's' and the other for words that need an 'es' to become plural. Let's dive in!

We usually make the word plural when we want to talk about more than one of something. But whether we add "s" or "es" depends on the word's ending. Here's an easy way to remember:

1. **Add "s" to most words:** For most words like "dog," "cat," "bird," and "cow," we add an "s" at the end to make them plural. So, " og" becomes "dogs," "cat" becomes "cats," "bird" becomes "birds," and "cow" becomes "cows."

2. **Add "es" to words ending in certain letters:** If a word ends in -ch, -sh, -s, -x, or -z, we add "es" to make it plural. This is because it's easier to say with an "es" at the end.

- For example, "church" ends in -ch, so it becomes "churches."

- "Fox" ends in -x, becoming "foxes."

- "Wish" ends in -sh, so it becomes "wishes."

- "Pitch" ends in -ch, too, so it becomes "pitches."

Finally, there are regular words like "cake," to which you just add "s" to make it "cake."

So, check the ending when you see a word and want to make it plural. If it ends in -ch, -sh, -s, -x, or -z, add "es." For most other words, add "s."
