Spelling Mentor software is the basis of our spelling curriculum. It contains grade-appropriate words for grades 2-4, 5-6, 7-8, and 9-12 along with a Spelling Companion booklet that introduces words clustered in sets, such as vocabulary words, words with double vowels, words with vowel blends, words with prefixes, and words with suffixes. For most sets, the booklet gives introductory information along with spelling rules or conventions.
