It depends on the area, my school which is in the middle of New York state mind you, talked almost nothing about what happened to native Americans outside of the major talking points, and this was maybe 10 years ago.

Where as other schools would spend more time on this subject or other schools would spend very little time


However it's mostly common knowledge that the US as a whole spends very little time and effort on teaching the ACTUAL history and not the white washed bullshit we mostly are shown.
