1. Numbers and Reactions
Thoughts of making Mathematics and Science
accessible for the visually challenged

2. Agenda
About the Project
5 Areas of Study
Way Ahead

4. Who all should study math & science?

5. Mathematical and Scientific aptitude
is sight independent.

6. Ground Reality
The gap between the need and reality

7. Two Kinds of People
1. Who believe it is not completely possible
to teach/learn Math & Science concepts
to the blind and low vision.
2. Who believe that the blind do not need
these concepts.

8. Research conducted by Xavier’s Resource
Centre for the Visually Challenged (XRCVC)
as part of the Vision for India (VFI) Project
of the Tech Mahindra Foundation.
