Show of hands
A show of hands is a common voting method used in committees and other informal or small gatherings for voting. It is more precise than a voice vote but does not require members to leave their seats. However, it does not count as a division of the assembly, and is not always as effective as a rising vote in causing a maximum number of members to vote who have not done so.
