We use www.time4learning.com for times like these. It's a fully interactive web based curriculum that goes from K-8. It has all of the core subjects and you can differentiate as you choose. The kids work at their own pace, the directions are very well done and they ca for the most part just have at it. My DS6 is extremely intense and this program saved my sanity. They have a free trial and sample lessons that you can check out.
