Just as I feared! Thanks for the detail, LynneV, that's very helpful. I'm not exactly received with roses and champagne when I arrive at DC's school to discuss math, so having that information will help counter the inevitable appeal to the authority of 'everyone' who is so impressed with this magnificent program.

aeh, the one review I had found described it as 'discovery math' which made my heart grow cold after everything I've read on this board about EM and Chicago Math.

I'm going to make a special point, now, of being nice to poor anthropomorphized 299...
