Abstract
Averaging over imaginary quadratic fields, we prove, quantitatively, the equidistribution of CM points associated to 3-torsion classes in the class group. We conjecture that this equidistribution holds for points associated to ideals of any fixed odd order. We prove a partial equidistribution result in this direction and present empirical evidence.

Acknowledgments
The problem of proving equidistribution was suggested to me by graduate advisor Soundararajan. The possibility of calculating a negative secondary term related to k-torsion was suggested to me by Akshay Venkatesh.
