The Teacher Resource Books include teacher's guides for the lessons, reproducible tests and reviews, vocabulary activities (including word webs and semantic maps), options for group or individual instruction, pacing options, and answer keys for the tests and Student Book exercises. Tests are designed to prepare students for standardized tests; the format is largely multiple-choice. There are tests for each lesson as well as cumulative midterms and finals. At the upper levels (grade 9-12), each test also features a SAT Sneak Preview section in which additional practice is given in preparation for standardized testing. Wordly Wise 3000 book numbers correspond with typical grade levels (unlike the original edition, Wordly Wise, and the first edition of the 3000 series where it was necessary to add three to the book number to get the grade level).
