Edubuntu
Edubuntu is an officially supported edition of Ubuntu created to fulfill the needs of children, students, parents, teachers, and schools. The full ISO is so large (at over 3 GB) that you have to burn it onto a DVD (or a high-capacity USB thumb drive, as long as you make it bootable) instead of a CD.
However, using the process outlined at the start of this chapter, in the section Adding Edubuntu, you can opt to just install the main programs from the distribution, which are only an extra 200 MB or so to download.
The distribution comes with over a dozen educational programs, such as Tux Paint (see Figure 15-8), which you can access from the Applications → Education menu.

The full edition supports the Linux Terminal Server Project (LTSP), for networking students’ computers with a teacher’s in a classroom environment. Explaining how to use it is beyond this book’s scope, but full details are available at http://edubuntu.org.
If you have young children, I definitely recommend installing the Edubuntu programs.
