It really should be in your bylaws. However, in your case, I'd consider history and parent expectations (and then I'd firm up the bylaws).
Our bylaws require that elections, changes to the bylaws/constitution, and the the annual budget be approved at a general meeting. I think most would agree with that.
Otherwise, the power to make day-to-day decisions rests with our board. But note, my group is one where the general membership only meets twice a year and all the primary business is handled by the Board. You need to check into what's been done in the past and what your parents expect.
Beyond what we've stated above, anything truly controversial or impacting the organization at highest level (i.e., disbanding, changing our purpose) would certainly go before the general membership.
Maybe you should set a precedent. You could form a committee to make a clause for your by laws on what should be decided on and when and if in doubt take it before the general members.
I had this problem when I first became president, I had it too when I resigned, but if it was small and would benefit the kids and not put anyone out then the board decided on it. Larger issues I took before the general. Most of the time before any decision was made I would ask the opinions of the parents, teachers, and the board members. To get to the point, I didn't plan any elobarote activies or spend a bunch of money without bringing before the members.
I am unsure of what votes we should hold in private executive board meetings and which are to be open to the members. Our bylaws don't state what is voted on in general meetings. What do you do? Thanks.
