Edubuntu is a customized version of Ubuntu aimed at children in educational environments. According to the distributions homepage, Edubuntu is "Linux for Young Human Beings." That works out well for me, since I have three of those in my house. I homeschool my children and use Edubuntu on a couple of our computers. My boys love having an operating system that was designed with them in mind, and I appreciate the way its applications encompass the total learning process.
Edubuntu is based on the Ubuntu Linux operating system and geared for a wide age-range of children from youngsters just learning to read all the way through teenagers getting ready to enter college. It comes bundled with the KDE Edutainment Suite and dozens of other applications and tools to enhance learning in virtually every school subject -- math, reading, art, computer science, language arts, and more. Edubuntu's default interface is GNOME, but KDE is also available. While Edubuntu used extensively in classrooms across the globe, it is easy to install on a laptop or desktop computer for home use.
