Thanks, guys.
I just feel so fragmented jumping constantly between them and each one wanting to know "what do I do now, I'm finished". I think it would be better to work with the 8 yr old in the morning and let the two little ones play and then work with my daughter after lunch and let the boys play (my youngest is still in pre-school so we only do school with him when he asks so as not to push).
Thanks again

It might only help with your older two children but this year, I gave each child a whiteboard and they divided up by coursework and day. So, I'll refer them to their whiteboard when they need help. Sometimes, it's a matter of them not knowing what to work on for a given but I've tried to build work boxes for them too. So, my younger son has all his math work in one box with a semester's worth of schedule sitting on top of the pile. He can check his whiteboard to see if he needs to work on health, or Latin or whatever. If they work ahead, they mark ahead on the whiteboard. It doesn't completely stop the questions and interruptions but I hope it's teaching them some self-pacing.
