Adding the Suffixes -s and -es

Lesson Plan - Get It!

Audio:

The letter s can make two sounds.

The most common sound for the letter s is /s/ like in the word snake. Sometimes, the letter s makes the /z/ sound when added to the end of a word, like in the word bugs.

Say the word snake out loud. Listen for the /s/ sound.

Now, say the word bugs out loud. Listen for the /z/ sound.

In this lesson, you will read and write words with both sounds for s as you learn more about base words and suffixes.

A base word is a word that can stand alone as a word and makes sense.

Sometimes, you will add a suffix to the end of the word. You can add an -s or -es to the end of a noun and a verb.

Explain in your own words what a noun and verb are.

You should have said a noun is a person, place, or thing. The verbs in this lesson are action verbs. A verb is a word that names an action.

Watch this video to learn more about adding s and es to a word.

• When do you add -es to a word?
• Why do you add -s or -es to a verb?
• Why do you add -s or -es to a noun?
