There are some websites where you can donate to, such as:

Recommit2Kids Campaign
Weiss Institute

However, donating isn't the only way to help.

Even though donating does seem the only way to provide the the underprivileged, there are other ways too. You can also create things with the talents you aready have, even little things like short videos, coding small programs, or even drawing posters to raise awareness about it.
