3rd Grade Worksheets

Our 3rd Grade Worksheets collection provides printable practice for kids around ages 8–9 who are strengthening reading, writing, and math skills. Homeschoolers, afterschooling families, and caregivers will find vetted, secular worksheets that reinforce multiplication and division, basic fractions, reading comprehension, grammar, and paragraph-level writing. Every set is reviewed for developmental fit, clarity, and alignment with evidence-based approaches so the work supports understanding rather than busywork. Use the filters to sort by subject, specific skills (multiplication facts, word problems, main idea, punctuation, etc.), and purpose (warm-up, targeted review, or enrichment), plus learning needs like ADHD, dyslexia, autism, or 2e. Many families integrate these worksheets into a broader curriculum or use them for quick check-ins. If you’re unsure which third grade worksheets will actually help your learner, Modulo’s AI learning concierge can suggest a focused selection.
