hello, here : http://mageia.org/wiki/doku.php?id=sigedu you have the wiki with the lists of "Already packaged" and "To be packaged". I take the software of edubuntu and those here ( http://svnweb.mageia.org/packages/cauldron/task-edu/current/SPECS/task-edu.spec?revision=98765&view=markup )
Of course, the educational version of Mageia should be easy to use for parents and kids. I know a lot of parents with windows, who use live cd of educational linux for their kids. I will continue my list with the edu.kde.org softwares and then i will see the website see you mammig
