Fifteen shared lessons, A00–A14, teach the investigation skills. A00 includes the placement tool. Each single lesson has an entry bridge, so you can address a particular skill without buying earlier lessons.
Each grade case investigates two word-part families through five suggested sessions. It includes a prerequisite bridge, teaching directions, cards, practice, an original short mystery, a learner-only PDF, an independent check and a key. Grade 8 Case 24 is a research capstone.
Each annual grade bundle follows a 36-week supplemental calendar with cases, reviews, application and checks. Multi-year bundles combine grade content and include shared supports once.
Preview before you choose

Before buying: A single case is already included in its grade-year bundle and any multi-year bundle containing that grade. Annual bundles repeat shared supports. Repeated word parts across grades are intentional review and extension, not all unique new roots. The earlier nine-week intensive is a separate edition.
Teaching sequence
Teach A00–A08 first, then cases C01–C06. The sequence continues through review, Field Work and quarter checks. A09–A14 return at the indicated points in the annual calendar. Single cases include their own entry bridge and materials, so no previous purchase is required. Suggested timing is a planning estimate pending classroom piloting.
Yes. The Academy lessons build the word-investigation routine, and grade cases explore word-part families in context. Preview the grade case lists to see the particular families and sequence. The curriculum is supplemental word study, rather than a complete reading or spelling program.
The free starter and grade previews are available to review. Teachers and families can examine the teaching directions, learner pages and word-study approach before considering a future purchase. Paid downloads, prices and license terms remain pending release approval.
For teachers and families
Editable Word files let you adapt text, tables and prompts. Complete print PDFs and separate learner-only PDFs support distribution without accidentally sharing keys. Illustrations are raster images. A09 also includes an editable PowerPoint sorting activity. The PDFs are printable, not fillable or certified PDF/UA.
For a single case, prepare the supplied learner pages and study cards, plus a pencil, scrap paper and dictionary when the directions call for it. Plan five short sessions, approximately 20 minutes each; actual time still needs a classroom pilot. No special app is required for the print activities.
