An "education edition" of Minecraft is to be launched by Microsoft.
The product will offer teachers new ways to use the world-building video game in a range of subjects.
Microsoft paid $2.5bn (£1.8bn) for Mojang, Minecraft's Swedish creator, in 2014. And late last year, it bought the four-year-old MinecraftEdu version of the game from Finland-based independent developer TeacherGaming.
