Yes, I had a feeling they would click. I requested this teacher for DS. I know her from my mathlab days when DD was in 2nd grade. She is one of the only teachers who was doing regular mathlabs then and she gave me some good advice on how to run one in DD's class.
So not only is it working well, but it's working well because you followed your experience and instincts. It sounds to me like you can sit back with some chocolate and champagne (or whatever makes you happy) and celebrate! You've had a long road to get here, so enjoy it. There will certainly be other challenges along the way, but maybe you don't have to go hunt for them right now!
