My dd is 6 and in grade 1. We were letting her do her accelerated CTY math alone but then found some problems. Because it was computer based, she was trying to do everything in her head. I started sitting with her and helping her to use a worksheet to write out the problems. After writing out a few, she was better able to understand them and then do them in her head.
I think with some kids, like VS, it is good to work with them on these online programs during certain parts. Hence, not totally in isolation.
