Workbooks for 9th Grade

Our Workbooks for 9th Grade collection supports teens around ages 14–15 as they transition into high school-level expectations. Homeschoolers, afterschooling families, and caregivers will find vetted, secular workbooks that reinforce algebra I or geometry, reading complex texts, grammar, and structured writing skills. Every workbook is reviewed for developmental fit, clarity, and alignment with evidence-based instruction so you can add practice strategically rather than piling on hours of extra work. Use the filters to sort by subject, specific skills (equations, proofs, text analysis, essay structure, etc.), and purpose (review, challenge, or test prep), along with learner needs such as ADHD, dyslexia, autism, or 2e. Many families pair these workbooks with online courses, live classes, or tutoring. If you’re unsure which ninth grade workbooks will actually help your teen, Modulo’s AI learning concierge can recommend a focused selection.
