Elizabeth - I think you are the only person who knows how much pain is involved with your foot. If it is too painful to enjoy vacation then you know your choices are very limited.
I just tried using Khan with DS9 again. It is highly recommended. However, it was a total failure. After 15 minutes he was in tears. I think Khan is a wonderful learning site and totally free, but the learning style just doesn't work for DS9. I'm a tiny bit frustrated because one of my top curricula picks that we have successfully used the past 2 years switches to using Khan in 5th grade. I am going to have to find something else to replace it.
Time to pick DGD6 up from school for the very last time this year. Saying goodbye to 1st Grade. Public School is officially out here.
