I don’t think the teacher cares one way or another. The feds have decided that, if you take federal dollars, your school system will include this crap in the curriculum or you lose the money. The teacher, being a good union minion, is just doing what she’s told. Or, she’ll lose her job.
According to what I’ve read common core mandates that every single part of curriculum must be taught. A teacher may add to it, but no more than 15% of total content can be anything other than the common core content. However-not a single word can be eliminated from the common core material.
