Singapore Expats

We are an American family taking our 11yo daughter out of school for a year of world-schooling between 5th and 6th grades. We will be travelling as a family in Cambodia, Thailand and Laos until mid-August, and in mid-September we are due for a dive trip in the Lembeh Straits (N. Sulawesi). We are considering spending the interim month in Singapore and think it might be a good place and time to let our daughter enroll in a course or camp--to be with other kids her age for a bit, and also to learn something new or hone one of her other hobbies (she's a gymnast and plays guitar, etc.).
I am looking for on-the-ground suggestions about where I might be able to find camps or courses in the mid-August to mid-September time frame. We would be interested in gymnastics, martial arts, drama, traditional all-around camps, creative arts . . . even math!
If there are any moms out there with suggestions, we'd be most appreciative of your specific, firsthand knowledge!
Many thanks.

here are a couple of places that run holiday programs for the summer in relation to the arts (drama, dance, painting) ... my kids are younger but have friends with 10, 12 & 13 yr olds who love center stage. we do art boot camp and they run the big kids class at the same time.
