Glad to hear it. Common core is the educational equivalent of dog crap.

FWIW, I think the infamous Question #2 is a bit much for a 5 year old ... I had to stare at it for a while. Just for aesthetic reasons, I would have answered “Open Square”, but it’s not correct.

Speaking of 5 year olds, Dad showed me how to make a Mobius Strip when I was 5. Absolutely fascinating. Are you familiar with the “Klein Bottle”?

I wasn't until now ... not as fascinating .. it HAS a beginning and an end ... it's just within itself.

I can fill that bottle up and put a cork in it.
