Grade 3
homeschool curriculum.

Third grade is the year academic gaps start to compound. A kid who hasn't locked in multiplication facts struggles silently for years afterward. Cullinan uses spaced repetition and end-of-unit tests to make sure that doesn't happen.

The Cullinan approach

3rd grade is where end-of-unit tests start to really matter. We auto-fire one every 5 mastered lessons in a subject — mix of multiple-choice, short answer, spoken, and a short essay — so you know the mastery is real, not just lesson-by-lesson cheer.
