Software Suggestions for Elementary School Workstations?

krog asks: "I've recently signed a contract with a local middle school to replace their aged Apple /// cluster with a roomful of IBM Aptivas running Linux 7.3. Now surely I will be installing such ease-of-use tools as KDE3, Gnome, and screen, but I am looking for suggestions of other software to install. Anyone know of any good text editors/BASIC interpreters/shells/etc suitable for eight-year-old children?"
