What's in the Sixth-Grade Kit This year's kit includes a marble-powered computer that teaches binary logic — and that's just the STEM. Math covers decimals, percents, and ratios. Your child will build serious typing skills, work through formal logic and fallacy detection, and read literature that asks harder questions. Social studies in the classic kits focuses on U.S. government and civics, while nonreligious kits cover ancient civilizations. Science goes deeper into human anatomy — with puzzles and reference books alongside the core curriculum.
