Speaking and Listening SL.K.3
Ask and answer questions in order to seek help, get information, or clarify something that is not understood.
While SL.K.2 is specific to text comprehension, this standard in general asks for inquisitive little youngsters. You probably won't be pulling teeth to get questions from these inquiring minds, so just encourage them to use their five Ws and one H (who, what, where, when, why, how: see L.K.1.D).
