3rd Grade Curriculum

Third grade is often when learning begins to feel more “real” to kids: they’re reading chapter books, writing longer pieces, and tackling multiplication and division. Our 3rd Grade Curriculum collection gathers vetted, secular resources that help homeschoolers, afterschooling families, and caregivers support this important leap with confidence. You’ll find core programs and targeted units for reading, writing, math, science, and social studies, plus creative and nature-based options that keep curiosity alive. Each resource is reviewed for developmental fit, clear explanations, and opportunities for hands-on practice so eight- and nine-year-olds can build skills without losing joy. Use the filters to sort by subject, format (all-in-one curriculum, books, apps, or kits), and learning needs including ADHD, dyslexia, autism, giftedness, or 2e. Many families mix structured practice with project-based learning from this collection. If you’re not sure how to choose the right third grade curriculum, Modulo’s AI learning concierge can help you design a plan that fits your child’s strengths and your family’s schedule.
