How a lesson works

Five steps, from curiosity to confidence

Every one of the 87 concept lessons follows the same rhythm, so students always know what comes next.

Step 1

Warm-up

A quick guess that gets the brain switched on before any rule is shown.

Step 2

Prayog Lab

Move sliders, toss coins, pour cones or tile a floor and watch the idea appear.

Step 3

Worked example

A full solution revealed one step at a time, at the student's own pace.

Step 4

Practice

Questions with hints and complete solutions, plus fresh questions generated every time.

Step 5

Sprint

A 60-second game with combos, XP and badges to lock the idea in.

The whole book

All 14 chapters of Ganita Manjari

Each chapter has concept lessons, Prayog Labs, exercises arranged like the textbook's (for example 12.1 to 12.4) with full solutions, end-of-chapter exercises and a printable answer key.

What makes it different

Built for how Class 9 students actually learn

∠

See it before you learn it

99 Prayog Labs turn every rule into something to explore: the midpoint theorem, Heron's formula, tree diagrams, Euclid's algorithm.

✓

Solutions for everything

All 863 questions have hints and complete step-by-step solutions, and every exercise set ends with an answer key.

12.1

Arranged like the textbook

Exercise sets follow the book's numbering, so homework and the app line up chapter by chapter.

★

Games that build habits

XP, ten levels, daily streaks, badges and 60-second sprints keep students coming back.

◐

Their colours, their way

Students pick a colour theme (Sunrise, Ocean, Holi, Forest, Galaxy or Classic), and dark mode is built in.

↻

Progress that travels

Progress saves on its own. A backup file or a short code moves it to another phone or computer in seconds.

Questions

Frequently asked

Does Ganitopia follow the NCERT Ganita Manjari textbook?

Yes. It covers all 14 chapters of Ganita Manjari Parts 1 and 2 for CBSE 2026–27, in the same order, and its exercise sets follow the book's numbering. The questions are written by Ganitopia, so use them alongside the textbook, not instead of it.

Is it really free?

Yes. Every lesson, lab, exercise, solution and game is free. Pro will add unlimited practice and chapter tests later.

Where is my progress saved?

On your own device, in the browser you use. Open "My progress" in the app to download a backup file or copy a progress code, then restore it on another phone or computer.

Does it work without internet?

Once a page has opened, its lessons, labs and questions keep working offline. Only the fonts need a connection.

Can two students use the same phone?

Yes. In "My progress", choose "Add a student". Each student keeps separate answers, XP and badges.

Is Ganitopia linked to NCERT or CBSE?

No. Ganitopia is an independent learning site. Ganita Manjari is a textbook published by NCERT.
