Tomorrow will present teachers with a number of “teachable” moments. To help you take advantage of those moments, Mashable has compiled a list of more than 20 online ways to enjoy Halloween. Among Mashable’s list of resources is the History Channel’s “History of Halloween” page containing videos, games and other resources.
