Here are some different activities and sites you can try while "homeschooling" during our time off:
The Cincinnati Zoo has a daily Home Safari at 3:00 p.m. (4:00 p.m. our time). This looks like a fun "Virtual Field Trip", plus they give an activity to do afterward. I believe you can go back and watch the past ones on youtube.
Social Studies/Art (Virtual Field Trips)
Directed Drawing Lessons
(I'm sorry that they're on their side, but I tried to turn it. It just didn't stay.)
