I have pursued a couple of online courses in my university and now my daughter is in a sort of an online school. I am homeschooling her and the internet is one major resource for her to learn. I make sure I try and find useful websites as well as worksheets online that help and have managed to come across some good ones such as a site which contains educational math games like these. These actually work as distractions for her rather than the usual pen and paper homework and she learns without realizing the fact that she is learning so it has been a win-win situation for me, at least till now.

Concentration can be a problem, yes. You've just got to focus on one thing at a time and set a routine to your day. It's all in the mind and all in your hands. You're the one who has to see what works for you and what does not.
