Our family subscribes to starfall, mostly for my dd (14, but cognitively about 3 y/o). She is not able to write, but can use the mouse quite well. The math section has preschool math (numbers 1-20 (I think), then 25, 50, 100, and does several activities for each. There are also several math songs, such as 1,2,3,4,5 Once I Caught a Fish Alive, and the Months of the Year). Place value, word problems, calendar, some brief composer info. My ds9 and ds7 both love to do starfall for math when they are done their MUS for the week. It is good review for 1st and 2nd grade math. There are also books to read, phonics, colors, historical songs, learning time, weights, symmetry, patterns, etc. It has been well worth the $35 for us.
HTH,
