Grade-by-Grade Overview

Elementary (K-5)

Build strong foundations in reading, writing, and math. Lessons use hands-on examples and visual learning. Focus on phonics, number sense, basic science concepts, and community awareness.

Start with Kindergarten

Middle School (6-8)

Transition to more abstract thinking. Pre-algebra and algebra readiness, close reading skills, scientific method, and historical analysis. This is when SAT/ACT skill-building becomes more explicit.

Start with Grade 6

High School (9-12)

College-preparatory content across all subjects. Algebra, geometry, advanced writing, lab sciences, and dedicated SAT/ACT preparation tracks. Every lesson shows which test domains it covers.

Start with Grade 9

Understanding SAT/ACT Alignment

Every lesson shows which standardized test skills it develops:

  • SAT Reading & Writing: Craft+Structure, Information+Ideas, Standard English Conventions, Expression of Ideas
  • SAT Math: Algebra, Advanced Math, Problem Solving & Data Analysis, Geometry & Trigonometry
  • ACT: English, Math, Reading, Science, Writing (optional)

This alignment helps you understand how each lesson contributes to your child's long-term college readiness, even in elementary grades.

Frequently Asked Questions

Is this really free? What's the catch?

Yes, completely free. We're funded by donations and believe education should be accessible to everyone. There are no premium tiers, no ads, and no data selling. See our mission page for more details.

Can I use this as my only homeschool curriculum?

Yes. Our curriculum covers all core subjects (Math, ELA, Science, Social Studies) for grades K-12 with content aligned to common educational standards and college readiness requirements.

How do I know what grade level to start at?

Start with your child's current grade. If material seems too difficult, go back a grade to build foundations. If it's too easy, move ahead. There's no penalty for working at your own pace.

Are the lessons aligned to Common Core?

Our lessons are designed to meet or exceed common state standards. More importantly, they're aligned to SAT and ACT requirements, which are the ultimate measure of college readiness.

Can my child work independently?

It depends on age and ability. Elementary students typically need guidance, while middle and high school students can often work independently. Each lesson includes explanations, examples, and self-check quizzes.

How do I print lessons?

Use your browser's print function (Ctrl+P or Cmd+P). Our lessons have a special print stylesheet that removes navigation and optimizes layout for paper.

Can I use this offline?

Yes! After visiting a page once, it's saved for offline access. You can also print any lesson as a PDF for completely offline use.
