Edubuntu

Edubuntu takes regular Ubuntu and adds a preselected library of education-focused applications -- covering subjects from math and science to language learning and geography -- aimed at making a classroom-ready or homeschool-ready computer available without a teacher or parent needing to hunt down and individually install each program themselves. Because it's an Ubuntu flavor rather than an independent distribution, it inherits Ubuntu's LTS release and support model along with full compatibility with the wider Ubuntu software ecosystem for anything beyond the bundled education apps. It's a lighter-weight alternative to Debian Edu's full school-network-infrastructure approach, suited to a single classroom or home rather than a whole-school deployment.
