A Crow with Flaws
The variant vowel /o/ spellings a and aw, as in ball, walk, and saw are fairly reliable in terms of the sound they represent. They represent the /ah/ vowel sound. The other letter combinations that make the same vowel sound include o as in lost, augh as in vault, and ough as in thought.
Please note that the decodable book A Crow with Flaws should be used after lesson 62 when students have the necessary tools to read it.
