Lock Down Drill

We had our first lockdown drill today. During a lockdown the children sit quietly in the cubby area. We turn out the lights and lock the classroom door and close the blinds. We tell the children we need to practice lockdown in case an animal gets into the school. We tell them we sit quietly with the lights out so that we don't frighten the animal in the hallway.  We explain that we have to practice this, just like we practice a firedrill.
The kids were awesome and very quiet.  We do two lockdown practices each year.
