So just use cycles instead of degrees. Simple fractions or a circle. Fractions are already taught to young children as "how many pieces a circle[1] can be divided into." It would seem to kill two birds with one stone.

I think most kids who even study pre-Calc could handle applying a conversion of "2pi" from there.

Good point. I forgot we learned about "slices of a pizza" that early.

By the way, the history of the degree is somewhat interesting:
