I liked Aleks.com for my kids....three in a row correct for mastery but the assessment cycle assured that they really had altered it. They really liked the pie chart and the self determination of what to work on. Both kids used it as a supplemental program...one to our homeschooling work and one who was in second grade working within his classroom using a third grade book.
