This document provides a teaching sequence for introducing the letter sound "s" to children. It suggests using visuals like posters and flashcards to help children recognize the sound. Teachers should model making "S" shapes with their hands while saying "ssss" to help children remember. A song is recommended as a fun way to build sound confidence. Worksheets can help children practice writing capital and lowercase "S", first with their finger and then with a pencil. Reinforcement activities identify words beginning with "s" using technology and individual worksheets.
