I have a DS in Pr 1 this year. Although he is already very chatty by nature, I find that by asking lots of Qs about his day in school which entails him sharing details etc, it allows all of us at home to know alot about what's happening in his class and in school.

Preferably when asking Qs, ask leading Qs - ie. not Qs that just entails a "fine" "ok" or yes /no" responses. So for instance Qs like; "what are the names of your classmates who sit beside you in class?" "what did you do during PE lessons", "what was done in art & craft class today?" "what was for recess today - what did you buy?"
