My world is still pretty simple in this regard, as I am just dealing with DS4.5 & a toddler. DS4.5 has his own login on the laptop, and I have saved a handful of sites to a favorites so he can click them. Occasionally I delete or add something. As for worksheets, I have a box like a magazine holder by the boys' little table. It has 2 sides, and I rotate coloring books on one side and drawing paper, construction paper, and worksheets on the other side. There is also a small basket in the kitchen with lacing cards, alphabet flash cards, & pattern blocks. This probably doesn't help you much, but at least it's a bump. ;)
