There are lots of different options below, all from Code.org
This year, there are four Minecraft themed tutorials to choose from. In Minecraft Adventure, you will program Alex or Steve to explore an Minecraft world. In the Designer tutorial, you will create your own “Minecraft” experience where you can program the rules that make the game work. You can make chickens that drop gold, or zombies that run away instead of attacking. In Voyage Aquatic, Alex or Steve will explore and build underwater worlds with code.
