It could just be a maturity thing....DS came home from his accelerated math class at that age and said that he only answered if there was a pause of 20 seconds or so with no one else having the answer,
.
My DS (5) is doing the same thing. It is funny, even his teacher already caught on: she asks question, children raise their hands- wrong answer or nobody knows- little pause and DS is rasing his and giving his answer. He does this ever since the beginning of K. I asked him about it once and he said he wants to give the other children chance...LOL
