Where can I get a teaching station?

There are 2 types. The basic one that does the starter and intermediate classroom and the ones for advanced classrooms that later on you build into individual rooms.

The first one is the learning stone and I think that is free right at the start.

The rest are scattered through each tree and usually cost between 1500 and 1900 - just to point you in the general area and look like this:
