Until they understand language patterns, students with dyslexia will continue to struggle. This important resource provides a flexible and systematic program for teaching language structure to students with dyslexia. It offers clear explanations, step-by-step instructions, and an abundance of well-organized lists for teaching reading and spelling. At the heart of "Keystone's" approach is a student notebook. Students use the notebook as a reference to materials to be reviewed, a visual aid for learning the organization of language patterns, and as evidence of their mastery of the structure of the English language. Students practice both writing in and reading from their notebooks, thus reinforcing their new encoding and decoding skills. "Keystone" begins with a section on consonant and vowel sounds. Students then progress to syllable patterns. Prefixes, suffixes and irregular words further increase students vocabulary. Word lists provide students with plenty of reading and spelling practice as they add new skills.
