Some Gwinnett County parents complained this week when they thought their middle schools students were going to be charged 10 cents an assignment, 20 cents for lost assignments and $10 for the use of their desks. The parents hadn’t received or read emails that were sent out about an eighth grade social studies class lesson at Shiloh Middle School, said Sloan Roach, school system spokeswoman. Roach said the students were studying Georgia history in the Colony days and the issue of taxation without representation. “The idea was to show students how it felt when you are taxed highly for goods and services,” she said. “It was a way to bring home to the kids what the colonists were going through.” Because of the confusion, a letter went home Wednesday, explaining that students weren’t being hit with any new fees, the spokeswoman said.
