Envirothon is compulsory. Geography Bee was “advised” for Vlad last year; of course, after winning, he didn’t need to be nudged again. I signed Frank up and said, “You’re coming to this.” I’m sure he’ll be enthusiastic next year after doing so well.
I don’t give them study assignments for geography, just remind them, if they’re at loose ends, that they could go look at a map or do a quiz.
Envirothon is different, more of a class, with meetings and assignments, and a commitment to your team to give it your best effort.
My niece told me that geography is no longer taught in public schools. Whiskey tango Halifax? They don’t learn cursive, either.
