We hadn't even gotten to multiplication yet, when a few months ago I asked her on a whim, how much is four 4's? She came back with 16 very quickly.
I asked her how she knew, and she said I'd taught her. I said, "I did, how?"
She replied, "You taught me that 4 + 4 = 8 and 8+ 8 = 16."
We have since done a bit of multiplication, but I'm still impressed. Seeing the program being used makes me realize even more how different it is, and how well designed it is. It doesn't look that different until you really scrutinize it, and its full worth doesn't come out until you have used it. It is even more apparent how well it works if you used a regular math program first.
I just bought all 6 years worth of Challenging Word Problems, as CassyT posted, they are being discontinued soon. I also bought next year's 2nd grade math.
After last summer's exodus of math facts from the brain, this summer we're doing Right Start math games a few times a week to keep the math facts from jumping out of the brain and running off somewhere. It is a fun way to review math facts, we're enjoying it so far!
