Answer
The Sonday System won’t work as well if the spelling component is omitted. NIH (National Institutes of Health) research suggests that spelling is an important component of successful reading programs. Spelling dictation is a focused multisensory activity that cements learning into long-term memory. It enables the diagnostic teacher to constantly monitor responses and know which sounds, rules, or generalizations still need practice or reteaching. Without the spelling component, reinforcement and accurate monitoring suffer.
