Re: JUMPSTART. I really like their product. In general, they are good for enrichment activities, but they aren't good for "teaching." The series offers lots of drill and grill/kill, in fun and entertaining ways. I particulary like their "Typing" CD - that is truly a fun way to learn how to keyboard.

"Reader Rabbit" and the "Blaster Series" are also very good for the same reasons. All three series seem to cover about the same information in similar ways.
