This document outlines a teaching sequence to teach children the "Ch" sound. It begins with using a poster to get the children's attention and have them brainstorm words with the "Ch" sound. Next, the children sing a nursery rhyme while acting out the "Ch" sound like a train. The sequence then focuses on phonemic awareness activities to identify, segment, and blend words with the "Ch" sound. This includes matching words to pictures and sorting words by those that do and do not contain the "Ch" sound. Finally, the children practice writing the letter "Ch" and filling in missing letters of words containing the sound.
