two hundred by threes

[clearwater]

OK, would you close your eyes? Now what I would like you to do is to softly, out loud, begin to count backwards from two hundred by threes. And as you do that, I'm going to put my hands on your shoulders and turn you around in circles.

Hi, could anyone answer the questions as below?

1. out loud? Does that mean to count out audiably, but softly the numbers?

2. two hundred by threes. Does it mean make the numbers for three a group?

For example, 200, 199, 198, then 197,196, 195, then, 194,193,192...

If no, could you illutrate?

Thanks~!

I've figured that out. Thanks!
