Here is a great interactive common core lesson plan complete with all materials.
The Lesson starts with a mini-dbq/scaffolding question worksheet. This worksheet is about how Christianity got to Rome through St. Peter. It leads into the Powerpoint presentation with intro notes to St. Peters basilica with many pictures and also goes into detail about the reasons for the SCHISM.
The activity is great for corporative learning and/or a close read.
There is a great graphic organizer that goes with the reading and a special Trick to help them remember the SCHISM.
It finishes up with a current event article about the Pope and Patriarch recently trying to bury the hatchet that dates back 1000 years.
