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 then practiced through words beginning with that letter. Words are grouped by families to reinforce patterns. Mastery is achieved through games, exercises and contests to keep learning fun for children. Guidelines include introducing word families, using pictures, substituting letters, and independent reading practice. Post-instruction includes spelling, worksheets, and meaningful activities to apply learning.
