In this game, you can learn and study while creating and exploring virtual worlds. It is a different app than regular Minecraft.
Download here. (Desktop, Laptop, Macbook, iMac, or iPad)
Once downloaded, log in by typing their Google username (USERNAME@humbleisd.net) and password. You may be asked to do so more than once. Inside the game, you can create your own worlds or join existing worlds. I suggest starting with some of the tutorial videos.
