Houghton Mifflin. SPELLING and VOCABULARY. Teacher’s Resource Book. Affix, Root, and Word Cards. Teacher’s Edition Book. Student Textbook. (very good with 3 hard 3×3 computer teacher resource discs). (this is missing about 32 pages in the middle- unit 21-27, 6 pages in beginning (unit 1) – pencil writing on about 30 pages) – maybe a handful of random other pages that might be missing.
