This is one keynote in a series of 101 keynotes which delineate 101 key words that every student should know. This system uses words that kids already know (or words that are easy to learn) to teach them the most essential roots and prefixes. So instead of learning roots and prefixes by flash cards, etc. kids learn them from the words they already know. This key word system is the fastest, easiest, and most effective way to teach students the word parts that will allow them to decode thousands of words.
