Both these CD's come with little books describing hands-on activities for learning skip counting. I, personally, like The Skip Count Kid's Bible Heroes best of all the skip count songs, both musically and mathematically. The music and singing are terrific—I could listen to it over and over. The phrasing of the skip counting is musical enough for children to easily pick up the patterns, and the Bible content actually says something worthwhile.
The content of both CD's is also available as MP3 downloads.
