Not quite sure what the Tower of Hanoi problem has to do with trigonometry.

We have one partial victory!!!

Our kids' (private, L.A.-based) school sent out a letter today to parents saying that they are switching their "core" program from EM to Singapore "Math In Focus". However, the victory is very minor: they're only doing it for K and 1, and leaving 2, 3, 4, 5, 6, 7, and 8 with EM & Chicago Math. Those grades will have to wait a while. We're not sure about the roll-out time table, but it might be only the class of 2020 that gets the benefit of this.

Still, partial is better than nothing.
