7th Grade Vocabulary Words
Seventh-grade readers are expected to move confidently among literary analysis, argument, research, science, mathematics, history, and civic discussion. This level develops precise Tier II and cross-curricular language while reinforcing context clues, word relationships, roots and affixes, multiple meanings, source evaluation, and evidence-based speaking and writing.
This independently authored 500-word beta curriculum is arranged in twenty pages of twenty-five words each. Words 1–300 include five cloze questions per page; words 301–500 remain fully visible and editable as list pages while the expanded practice layer is developed. Each row includes a subject-field label and an editable word-study note about a transparent affix, compound structure, capitalization, or dictionary base form. The supplied Grade 7 workbook calibrated difficulty and vocabulary-study skills only; all learner-facing definitions, examples, quizzes, and descriptions are original KSSR copy.
