I use Blender Flamenco rendering manager to run the classroom animation on my home render farm. Full setup and tutorials coming soon!
Flamenco is a free addon that the Blender development team releases. This software allows a network of PCs to distribute rendering frames to finish animation renders very quickly. You can check out Flamenco here:

I will have more in-depth tutorials on this soon, so be watching for more.
