I see some things that I suppose is common core. Like square root and making students break it all down to 2, 3, 5, 7. Then circle duplicates to take them out. Silly and prone to errors.
That being said, now they are solving recognizing 4, 9, 16, 25, 36 etc. Or maybe their not and I'm making my kid do it that way... oopsie if so
