Please take note that we offer a class set of 25 licenses of Minecraft Java Edition free of charge to our customers. The version of Minecraft we supply allows for multi player worlds in which students can continue to play and build even without the teacher being present. There are no limits to how many players can be in a world at any given time and we can supply several worlds to break things up a little bit. Unfortunately, the version we support does not work on mobile devices, tablets or Chrome books. We use the MultiCraft software to manage aspects of the game. Aside from having huge potential for instruction, it is a great way for kids to connect with their friends.
