What’s the best way to prepare a student who is ready for spring break? At St. Michael School, you re-enact the war between the barbarian hordes and the Romans that took place from 300 BC to 600 AD. The social studies project is something of a tradition at the school: Sixth-grade students playing Roman soldiers wield homemade shields designed in art class. They then are “attacked” by first-grade “barbarians” armed with foam toy swords. There are no winners or losers, but the combat is a prelude to the much-anticipated volleyball match between members of the eighth-grade class and a group of teachers.
