KG teachers teach English (the alphabet basically) Maths (numbers, shapes and colours). there is music and PE but not in a serious way. You think of songs/games to play yourself with them. There is no swimming in KG. Its grand really.
KG this year has gotten a lot tougher for the kids this year, they now have 2 written tests every week and one computer test. English consists of teaching them to memorize a certain number of sentences per week, type them in a computer test (with absolutely no assistance) and then write the missing word in their written test.
Maths, on top of number, colour, shape etc involves mental maths where they basically have to memorize up to 30 sums a week and then write the answer in a timed, written test.
It's fine, I enjoy it but it definitely is not as easy as it was in previous years and it will only become more difficult as they experiment with different ways to test the kids. It is very tough on the kids with poor memory and attention.
BTW, we didn't find out what grades we were assigned until near the end of the first week of training.
