Like many nine-year-olds, Stanley Strum spends a lot of time building things inMinecraft, the immersive game that lets your create your own mini-universe. The game has many tools. But Stanley is one of many players taking the game a step further by building entirely new features into the game. And, more than that, he’s also learning how to code.

He’s doing this with a tweak to the Minecraft game, called LearnToMod. Modifications like this, called “mods,” are a big part of the game’s runaway success. But this particular mod helps kids learn to create their own mods. For example, Strum built a teleporter that whisks him to a random location within the game world. Another lesson teaches kids to write the code to create a special bow that shoots arrows that become “portals” between different locations in the game, allowing them to reach spaces that would otherwise be quite difficult to access. It’s like being able to create your own cheat codes.
