Grades
One place to learn, Pre-K to Grade 12.
Not a pile of worksheets to search through. Every course runs chapter by chapter, in teaching order, so a family can start at the beginning and go straight through with no gaps. High school is named courses: Algebra 1 up through AP Calculus and AP Statistics; Biology, Chemistry and Physics, each with an Honors track; Physical, Earth and Space, and Environmental Science.
Subjects
Everything they need to keep learning.
| Subject | What it is | Lessons |
|---|---|---|
| Math | Complete, Pre-K through differential equations. Every figure is a manipulative the child moves before a symbol appears. | 933 lessons |
| Reading | Passages, vocabulary and comprehension, with read-aloud on every line for a child who is still decoding. | 233 lessons |
| Science | Every lesson opens with a phenomenon and an investigation; the explanation comes after. Still growing. | 607 lessons |
| Life Skills | Money, decisions, feelings, being online, independence, work and community. Free in full, no account. | 128 lessons |
Two ways to learn
The same lessons, either way. The difference is who sets the week.
Self
Learn on your own, at your own pace.
Open any lesson. Finish it, and it comes back as four short homeworks across the week, so the idea stays. A parent sees every child’s progress on one page.
Class based
Meet once a week. The homework follows the class.
A teacher covers a lesson with a small group, live. From class day that lesson is the week, and the four homeworks land at home on the days after. Nothing to set up.

Materials not used
A learning app without the addiction loop.
No ads
Nothing on this site is trying to sell your child anything. No banners, no rewards to buy, and no third-party analytics.
No streaks
No points, badges or timers. A lesson ends when the child has understood it, and nothing nags them to come back.
No child accounts
A parent or teacher holds the account. Children never sign in, and nothing about a child is collected.
Education first. Engagement second.
For parents
You do not have to become the teacher.
The family pageOne row per course. A filled square for every chapter check passed.
Practice sheetsEvery lesson, on paper, with the answer key.
Family progress
What each child covered, and where they stopped.
Printable worksheets
Every chapter, with answer keys. Some days you want it on paper.
Word problems
A page of them for any lesson, printable too.
The guide
Two parents walked through everything. Twelve minutes, jump to any part.
Do not just solve problems. Make your own.
A child sets out seven counters and asks “how many?”; Cogito works it and explains the answer. Then: can you make one for your parent?
Life Skills
School teaches subjects. Life requires skills.
Real situations and real decisions, with no multiple-choice right answer: a choice is strong, workable or risky, and the lesson shows what follows from it. Eight domains, from Pre-K to Grade 12, every lesson free with no account.
- Money
- Thinking & Decisions
- Self & Emotions
- Communication
- Online & AI
- Everyday Independence
- Goals & Work
- Community
Conclusion
Give your child something worth exploring.
Ten minutes in a lesson will tell you more than this board can. Chapter 1 of every course is open with no account, and until 31 December 2026 so is everything else.
No card. No child account. No ads.
