Here's an example at Nicolet High School, one of the best paying in Wisconsin.
I'm leaving off the full names, but it is in a searchable database here.
Salary for a teacher named Christopher is $78,591, with benefits worth $34,980 for total compensation of $113,571.
A physical education teacher in the Elmbrook district named Mark has salary of $64,555 and benefits worth $30,595 for a total compensation of $95,150.
An elementary school teacher named Rebecca in the Waukesha School district is paid $57,006 in salary and $32,553 benefits for a total of $89,559.
Your range of examples explains the $56/hr total avg compensation then, assuming 9 months of work - although I doubt every state compensates teachers as well as Wisconsin does.
