  prefix worksheets for 3rd grade: Power Tools for Literacy Verena Rau, 2020-10 The 300 systematic, engaging lessons in the second edition of Power Tools for Literacy are aligned with the Orton Gillingham method and the Common Core Reading Standards. Become an expert in teaching phonics in the context of syllable patterns and showing students how to analyze or chunk words into phonemes, syllables, base words, prefixes, suffixes, Latin roots, and Greek elements. Mastering and blending these phonograms and morphemes enables students to decode and spell one-syllable and polysyllabic words with ease and accuracy.A report by The National Institute of Child Health and Human Development states, For those children who are at risk for reading failure, highly direct and systematic instruction to develop phonemic awareness and phonics skills is required. In keeping with this principle, Power Tools for Literacy follows an explicit progression of phonics skills proven successful with struggling readers, students with learning differences or dyslexia, and English learners.Designed for grades 3-12, this program lends itself to individual or group instruction. The look and feel of the lessons is appropriate for any age group; material that appears tailored to young children has been avoided.Power Tools for Literacy uses a variety of interesting activities to cover these key topics and more:Short and long vowels with consonant blends and digraphsR-controlled vowels, diphthongs, and vowel digraphsSyllable patternsRules for dividing polysyllabic wordsCompound wordsReading, spelling, and defining 50 suffixesSpelling rules for adding suffixes to base wordsVocabulary enrichment by reading, spelling, and defining 50 prefixesAccented and unaccented syllablesFree and bound morphemesLatin roots and Greek combining formsWeekly spelling lists that incorporate high frequency sight wordsThe unique aspect of Power Tools for Literacy is the use of syllable codes. Each type of syllable has a code abbreviation. Utilizing codes in conjunction with a multisensory technique reinforces the structure of previously covered concepts and builds in review to achieve automaticity.This program is only one component of an effective reading program. It should be coupled with a literature-based curriculum, accompanied by intensive vocabulary development.
