Online learning/apps for 4yo ADD

[Artechim]

DS sat down and worked his way through half of reading eggs in about a month when he turned 4 so it can be done by littler kids but I find DD needs me nearby to help with it. She does love the maths seeds though and can do that by herself. There are also lots of eggy apps for tablets. I usually get the free ones and if they are rubbish they just get deleted.
