I found out that it was MCP Mathematics by Pearson. And it is centered around the core curriculum that is being adopted by many states, including ours.

On aside, we just got back from Cancun. There was a girl, 9, in third grade that DD7 befriended. The mother was a 4th grade teacher. She had bought the Kumon grade 3 math state test practice (which all 3rd graders take, and then another state test in grade 4). This girl was trying to do the multiplication and DD apparently was trying to explain multiplication tables to her. I was not there. When I walked up, a conversation started with the mom about math curriculum. My comments that they needed to increase the difficulty, the mom was stating that it was too hard already for most kids. And mentioned DD was an exception. I have to say, that I thought this was shortsighted or are ND kids really that incompetent that they cannot compete with millions of Chinese and Indian kids doing multiplication in grade 2?

I think that we should push the envelope. Maybe I am wrong.
