The Fuller Approach is a method for teaching reading that combines alphabet, phonics, and whole word instruction. It involves first teaching letter sounds and formation. New letters are introduced along with example words beginning with that letter. Multisensory exercises reinforce the letters. Next, word families are introduced by sounding out the pattern and presenting example words and pictures. Students read words in the family and substitute different letters. After teaching a family, students spell words from it and complete worksheets and activities to practice.
