Hi Mahisushma,
Below are some of the ideas that would be helpful to you...
1. Sapling Plantation - Going Green is the in thing now...
2. Adopting a govt school nearby your area and providing stationary/books/bags etc to the students
3. Home for the aged / Destitute children, check for distributing a gift basket consisting of all necessary/ essential items like (soaps, powder, paste, blankets(since winter is going to set in) whatever you think would be of use to them...) however the most important thing they care about is we able to spend some time with them.
4. Asking a group of employees interested in CSR to teach freely on weekends in any of the schools for an hour or so would be of great help.
5. Funding education of students who are needy is also a noble thing to do.
