Open curriculum
An open maths map for Classes 1–8
Every student on Takhtee gets practice from a topic map of school maths, Class 1 through Class 8. The map is open. You can read it, use it, and tell us where a skill is wrong.
This map is AI-drafted. Teachers are still reviewing it. It is not an official NCERT publication, and it is not a copy of the textbook. Don’t hand it to a parent as if NCERT published it.

The topics for each class live in the repository. We don’t copy them onto this page, so the site and the repo can’t drift apart.
What a skill map is
A skill, not a chapter scan
Each entry is something a child can learn and show, with the class it belongs to.
What comes before
Skills point at the skills they depend on, so practice doesn’t skip a step.
Open on purpose
The map is public. A correction in the repo can reach every institute using it.
