Personal counterfactual: I was smarter than my peers and didn’t skip any grades.
Result: I didn’t physically play with or date the other students.
Exceptions: I did play football and did Boy Scouts, but those were both after-school activities. Moreover, neither of them were strictly segregated by age. Football was weight-based, and Boy Scouts lumped everyone from 11 to 17 into the same troop.
Putting students in the same math class based on age (ignoring intelligence) is like putting students on the same football team based on age (ignoring size).
