Knomi
You already know area: it counts the squares that cover a flat shape. This rectangle is covered by 6 of them.
Stuck? Knomi goes back.
It finds the shaky step, fixes it, and comes back.

Let's go back to Dividing Decimals for a few minutes. Then Unit Rates will be easy.
Fixed. Unit Rates is yours, and Percents just opened.

What parents ask.
Every student, from kindergarten through Grade 12: elementary school, middle school and high school. Each grade has its own map, every topic in the order it's best learned.
Math, science and English, with more subjects on the way. Every subject works the same way: one topic at a time, and a tutor that goes back to fix a shaky skill first.
Yes, 100% free. There are no ads, no trial and no card to enter.
Not to look around. You only sign up when your kid starts a lesson, so Knomi can remember their progress.
No. Lessons are written ahead of time and every answer is checked by code. The AI only helps Knomi talk in a friendly way.

Grades 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 have a lesson for every topic. The other grades' maps are open to look around, and their lessons are being written now, the same way.
