The program begins with a quick review of consonants and then moves to vowels, decoding, spelling, and reading comprehension. Students are taught explicit, predictable strategies for decoding and spelling words. Worksheets, speed drills, and vocabulary tests provide continual reinforcement of concepts learned as well as a daily opportunity to read connected text. All student reading material contains fully controlled, decodable text to ensure student success. A built-in vocabulary component helps increase vocabulary while reinforcing phonics and spelling rules. Progressively difficult alphabetizing activities teach dictionary skills. Cumulative assessments occur at regular intervals, and specific remediation activities are provided for students who have difficulty. The last 25 worksheets contain paragraphs that teach students about U.S. history, culture, and government; comprehension questions are provided with every reading passage. Phonics Intervention is a decoding and spelling intervention program for struggling or below-level readers, from fourth grade to adult. Its goal is to provide students with the critical decoding and encoding skills necessary to be able to read and write independently. Author Lorna Simmons, a former classroom and special education teacher,worked closely with teachers in the field, testing the program across the country to create a program that is as effective as her enormously successful Phonics K-2 program.
