Free 3rd Grade Worksheets

Our Free 3rd Grade Worksheets collection gives families budget-friendly access to printable practice for learners around ages 8–9. Homeschoolers, afterschooling families, and caregivers will find vetted, secular worksheets covering multiplication and division, early fractions, word problems, reading comprehension, grammar, and paragraph writing. Every sheet is reviewed for developmental fit, clear layout, and alignment with research-informed approaches so practice strengthens understanding instead of adding confusion. Use the filters to sort by subject, skill (multiplication facts, fraction models, main idea, punctuation, etc.), and purpose (check-in, review, or enrichment), as well as learner needs such as ADHD, dyslexia, autism, or 2e. Many families pull just a few pages a week from this collection to complement more hands-on or conceptual learning. If you’re unsure which free third grade worksheets to choose, Modulo’s AI learning concierge can recommend a targeted set tailored to your learner.
