Unfortunately, I don't think instructions will help you in this case. All the parts are identical, so it's not like you're missing anything without instructions. It's just a matter of experience with things like this. So, let me share my experience with you: I'd assemble it from the top down like globes are, with all the pieces joined at the top. Work your way down to the equator, keeping things as even as possible. This will depend on how well you aligned the parts at the pole, so try to get that critical area as perfect as humanly possible. Otherwise, things will be out of sync and the parts will be out of alignment by a significant margin by the time you get to the equator. When you get the half-spheres finished, laminate an additional layer of paper on the inside to keep their shapes. You can use regular printer paper for this, and then just glue strips of it on the inside, following the lines of curvature. And after that, just assemble the equatorial trench and put the half-spheres on either side of it.
