My Kids live in both Thailand and the West and we are raising them bi-lingual.
But how to teach them both Thai and English in a way that 'speaks' to them ... certainly not through a text book.
Kid's Cartoons ... way to go.
We have had excellent success with both the fun and informative and educational cartoons designed to teach the kids numbers, alphabet, colours, shapes, objects names.
Now, there are many more English ones available then Thai and I don't speak Thai so welcome any Thai suggestions.
I have Boys who are 2 - 3 year age group, but much of the stuff is interesting for ages well above this. Heck, I even enjoy watching a few of them.
So, maybe you have Thai kids moving to the West or Western kids and want them to learn a bit of Thai ... I'll post what we watch and the methodology behind them.
I have downloaded them on a few memory sticks so that the kids can watch them at home, in the car or on that long plane flight.
To convert them I use the simple (and free) Freemake Video Converter Freemake Video Converter - Free download and software reviews - CNET Download.com
or any other software program you may have.
Good luck with the learning process and please fee free to add anything you may feel of value.
