The thing I hate most about teaching is when I set work that will take some time to do and the whole class just puts down their heads and work without speaking. I always get the urge to distract them just for something to do. I could almost hug the kid who puts up their hand to ask a question. Having time during class time was something I wasn't prepared for when I started to become a teacher. Sometimes I walk up and down the aisles checking work, but most of the time I just sit there in the silence taking it in.
Could you help your student neaten up his binder? Maybe buy some indices for him and help him label them and put work in the right place?
Good luck with your teaching practice
