Word Journeys by Kathy Ganske is a teacher resource on developmental word study that explains how to use spelling inventories and word sorts to build reading and writing skills. Instead of grade-level lists, it helps adults identify each child’s stage—letter-name, within-word, syllables and affixes, or derivational—and choose targeted activities. Originally developed for classroom teachers, the book has become a go-to reference for literacy coaches and interventionists. Homeschool parents willing to dive into its framework gain a powerful, research-based way to differentiate word study across multiple ages. The book is a single, mid-priced purchase, but it requires some study; in return, it can replace years of hit-or-miss spelling workbooks.
