Homeschooling the flat earth

Just wanted to start a thread for those to discuss their experience in teaching flat earth in homeschool.
Obviously, we are not going to find a school, even traditional, to teach it.
But I think there is a lot of hope when it comes to homeschooling children.

How have parents experienced this? Was it bad or good?

How have priests reacted to it?
