The second one is correct.
The first one is not quite the same as the one you put at the end in parentheses. The word "while" makes a big difference.
1. We played speaking English at the camp.
2. We practiced speaking English at the camp.
(Are both expressions correct? Any difference? Does #1 mean "We played while we spoke English."?)
