The Slingerland Approach revolutionized literacy instruction as the first whole-classroom adaptation of the Orton-Gillingham method. It offers a comprehensive, multisensory, structured literacy program covering all five pillars of reading. Unique to Slingerland, it includes handwriting for both manuscript and cursive, reinforcing kinesthetic pathways. The approach is adaptable for whole classrooms and individual tutoring, covering oral language, handwriting, phonology, phonics, encoding, spelling, morphology, written language, decoding, reading comprehension, and fluency. It uses auditory, visual, and kinesthetic-motor sensory channels simultaneously, helping students apply it independently to new concepts.
