This useful document contains a bundle of the different Letter Reader books.

Letter Readers follow the scope and sequence set forth in the systemic Teach Big phonics curriculum. The letters are grouped, according to which letters make the most words the quickest.

This allows for the highly frequent letters to create an abundance of words as students read. Each of the groups contains at least one vowel. Each Letter Reader book focuses only on the letters from that particular group within the scope and sequence. This promotes a systemic approach to teaching using the Science of Reading research.
