State law says otherwise, apparently.
Besides, who needs a foreign flag to learn where that country is, what they do, etc.?
I'd like to know if this teacher had a flag for every other country in the world.....
Exactly. Also, who needs to know what nouns, verbs, and pronouns are and how they are used to be able to speak? Who needs to know the table of the elements to get a job? Who needs to how to determine the circumfrence of a circle, or the area of a rectangle to budget their money?
Come on, you can't be serious. I hope you don't think that kids learning the flags of at least some other countries (especially major ones) is somehow taboo. That's the kind of mentality that produces ignorant, altogether stupid high school graduates.
