My point is, by the time students get to the area of circles, division by 2 should absolutely not be a source of concern. If they are scared by circles because of a division by 2, then you have already failed them when you taught them division. Throwing out all the good that tau does because teachers fail at teaching division to kids is totally missing the problem.
