We used low tech SG maths books until the end of 5th grade in their curriculum.
We then tried the Lure of the Labyrinth for fun.
Next the AoPS Pre-Algebra I & II while DD was a whole grade accelerated 4th grader.
Did the AoPS Algebra I (part I) so far and the Intro to Python during 5th grade.
Also tried Dreambox which DD found too boring.
SG Math was great no fluff - stuck to the basics and executed excellently.
First in Math was a hit until my DD ran out of incentives.
Khan Academy is OK and I applaud the guy for doing it but things are a bit simple.
Overall AoPS is the clear winner so far.
Lure of the Labyrinth helped DD make the transition from pure arithmetic to pre-_algebraic problem solving.
