My almost-11YO-son is math bright but not gifted. We've been doing Singapore since Earlybird, and he's just finished 5A. (We flirted with Saxon 1. We supplemented with Daily Math Practice in 2nd and 3rd, but I'm not sure it was necessary. We haven't supplemented with any of the Singapore extras.)
I'm going to be switching him to Dolciani, so I've been reviewing the Algebra I book. Last night I read him this story problem aloud:
To be called "Limited" a train's average speed must be 5 miles an hour more than twice the average speeed of a "Local". If the Limited travels at 63 miles an hour, what is the speed of the Local?
"That's easy," he answered. "Just subtract 5 from 63 and divide that in half."
His answer was so off hand and quick, my husband and I were speechless. We've worked lots of similar problems in Singapore, and I knew that he could do it on the white board with some time. And my husband and I would have immediately started designating variables and setting up equations. But for my boy, this was trivial.
And that's why I love Singapore math.
