As Karen has noted, I can wax pretty enthusiastic about Math-U-See. Here's what it looks like in our house. Jane is not in the picture; she prefers to take her algebra book off somewhere after she watches a lesson. I'm a floater, available to answer questions and prevent small unit blocks from entering the baby's mouth.
Rose didn't happen to have her dry-erase board out the day I snapped this, but usually she gets herself all set up with the markerboard, markers, eraser, and remote control before she turns on the DVD (as I described in this post). When she was seven, I'm pretty sure the markerboard was a huge part of math's appeal—that and the bubble gum. She really likes to work problems on her board while Mr. Demme is solving them on his. She pauses the DVD and works it out, then [snatches the remote away from her little brother and] hits play to see [because now she can't hear above his outraged shriek] if she was right.
Beanie, meanwhile, makes sandwiches.
