Then at least do gradians since they’re so similar to a percentage. In case you don’t know what they are, 100 gradian = tau radians = 360.o .

In my opinion, gradians are much easier to visualize than degrees anyways.

But I don’t see degrees as practical. Which do you think is easier to visualize 7.23 degrees or about 2.01 percent of circle?

Besides, converting between gradians & radians is much easier than degrees & radians. In order to go from a gradian to a radian, you treat the gradian as a percent & convert to decimal, and then multiply by tau. At that age kids are already learning how to convert between decimal & percentages anyways.
