High Frequency Words: A teaching plan
Traditional approaches tend to skip straight to practicing the spelling, but as they have missed the vital information in anchoring the meaning and analyzing the word, the only way to practice is with automatic recognition by showing the word on a flashcard or by copying it, letter by letter. This is learning without understanding. For children with poor visual memories, it’s unlikely to be effective, not to mention reinforcing the notion that the spelling is random and cannot be explained. The 3-step process is better!
