Read and write words with the digraphs sh and ch, hearing that two letters can team up to make one brand-new sound.
Sometimes two letters stand right next to each other and make ONE new sound. That is called a digraph. S and h together do not say "s" and then "h." They team up and say "sh," like the sound you make to ask for quiet.
C and h team up too. Together they say "ch," like the first sound in "chip." Once you know these two teams, you can read lots of new words.
Mastery looks like: They spot the sh or ch team in a word right away and blend it smoothly with the rest of the word, front or back.
Common stumbles: Sounding out s and h as two separate sounds instead of the one blended sh sound.
