Nikon D3100 lens broke?

The lense that came with my nikon fell and broke into three pieces, the mount, this thing that I'm guessing enables the lense to zoom in/out. Without that piece I can see the circits and wires and all that. And then finally the lense. Will I be able to fix it? Or should I buy a new one? I have insurance but I don't know if it covers that.
