Lumastery Curriculum by Grade

4th Grade Homeschool Curriculum

4th Grade (ages 9–10) · 79 structured lessons across 6 subjects, plus adaptive daily practice

Fourth graders work with bigger everything: multi-digit multiplication, long division, equivalent fractions, and first decimals. In reading, they start noticing how authors work — figurative language, theme, and the evidence behind a claim. Science deepens too, with investigation case files instead of just facts to memorize.

In development — not live yet

Writing: a structured K-8 writing program is designed and in an early pilot, but it is not yet part of the daily curriculum. The subjects above are what your child gets today.

Beyond the lessons listed here, every child also gets adaptive daily practice across individually tracked skills with spaced-repetition review, placement testing, and mastery-based progression — so your 4th Grade child works at their actual level, not just their grade label.
