Spelling is a vital component of reading. For young children, research clearly indicates that spelling supports learning to read, and for older children, it’s likely that learning about the meaningful relationships between words will contribute to vocabulary growth and reading comprehension (Moats, 2005/2006)
The goal of the English writing system is NOT accurate pronunciation but conveying MEANING. Teaching spelling systematically can dispel the myth that English orthography (spelling) is unpredictable, too confusing, irregular and simply “doesn’t play fair”
English orthography is NOT simple but understanding the rules/patterns and explicitly teaching them helps ALL students understand the structure and reason behind the spelling while and allowing the teacher to eliminate confusion instead of resorting to the adage “that’s just how it’s spelled”.
