Before I proceed further, just to let everyone know that my boy Daryl is Autistic, so, it is tougher for me and in your case it might be easier.
After some Don't, here are some Do.
1. Do go around book store and starts to read some of the text book for kid. You will be surprise it is not a "piece of cake" these day.
2. Do monitor your child work, it might be rubbish at the beginning. Make a date marking on their work and you be surprise how far they can progress in short time. I do it and I will put some photo soon.
3. Education is not only on books. Spending a weekend at Park or Zoo or places of interest is also a good way of exposing your child to the environment.
4. Do some exercise with your child such as coloring and origami (paper folding) and it will definitely foster your relationship with them.
5. For Chinese, you might want to let your child by-heart some Chinese "Tang Si", good for memory training. According to study, one who know about 2,000 Chinese character should have a fairly good command of Mandarin. Doesn't matter if they don't know the meaning, it will slowly come in. One important thing, don't under estimate your child. Parent roughly know what they will be heading for the rest of their life in their career but your child might be a Army General, Great Politician or Noble Price Winner, the million dollar question is, "Who knows". So, a little effort everyday is worth the while.
