This set of non-fiction Sound Families decodable readers covers r-controlled vowel sounds (/ar/ /or/ /ur/ /air/ /ear/). There are two titles for each sound. Within each reader, alternative spellings are provided (graphemes) for the target sound (phoneme). Children can identify the target sound in the text quickly as they have been highlighted and then compare the spelling across the sound family. Other words included are decodable at the phase level as well as common exception words in accordance to the progression.
