The ALEKS program depends on which program you choose. There are programs that just teach arithmetic without anything else and ones that do make a good attempt to add in geometry and algebra beginning with third grade. That is the track that my DD9 is on. They also do a pretty good job with decimals and fractions, much more than she was exposed to in public. They also have middle school geometry to give more of an introduction before high school geometry.
I also like Singapore math.
Math Detective, on the Hoagies Gifted Board might be promising. They are available in computer and book format. They are supposed to combine high order thinking, reading, and writing in mathematicss. Has anyone tried them?
