Lesson 20
-s /s/
The suffix -S spells /s/ and signals more than one
At this point, -S is being introduced only as the /s/ sound used to make a noun plural. The -S ending can also spell /z/ (e.g., dogs), which is introduced in Lesson 21.

Warm Up Our Ears
Say the sounds; students blend them into a word. Then say a word; students break it apart.
Blend it (teacher says sounds → you say word)
Break it (I say word → you say sounds)

New Concept
Today we learn that adding -s to a word can mean 'more than one,' like cat becomes cats.
Highlighted words are the ones to show and practice reading — tap one to hear it.
Today we are going to learn about the ending -S. When we add -S to the end of a word, it can mean there is more than one of something. For example, one cat is a cat, but two or more cats are cats. The -S at the end still spells /s/.
-s /s/
Adding -S to the end of a word can spell /s/ and shows there is more than one, such as and . The base word stays the same, and we just add S to the end.
How our mouth moves
The suffix -S at the end of a word still makes the /s/ sound, just like the letter S at the beginning of a word. Review the /s/ gesture, as needed: put your tongue right behind your top, front teeth and blow air out. Watch me /sss/. You try /sss/.
Sound wall
Review 's' on the consonant grid under the /s/ picture card; note that -s can also appear as a suffix.
