Maths | Subject Matter Expert for CBSE Classes 9–12 (Calculus focus)

I’m building learning modules for CBSE Maths, Classes 9 to 12, and I’m looking for someone to help design and structure them.
The focus is on understanding, not rote learning. Each module should explain why a concept works, and you should be able to develop certain diagrams that can help explain the concept easily

What you’ll do:
Break chapters into clear, logically ordered sub-chapters
Write concept explanations, & divide the sub-chapters into easily digestible bits
Suggest where a visual or interactive demo would help a student understand something (you don’t need to build it)
Check content for mathematical accuracy and alignment with the CBSE syllabus

What I’m looking for:
Solid working knowledge of CBSE Maths, Classes 9–12
Comfort with Class 12 topics, especially calculus: limits, continuity and differentiability, derivatives and applications, integrals, differential equations
Clear, simple writing in English
You don’t need to be a PhD or a senior subject expert. If you understand the concepts well and can explain them simply, that’s enough.
Teaching or tutoring experience is a plus

To apply, please include:
A short note on your maths background and any teaching experience
A sample: explain in 150–200 words why the derivative of x² is 2x, as you would to a Class 11 student
