I do not want to offend anyone who enjoys this...but my sons and I were really disappointed with this CD. It is not really rap - it's like Rap-Meets-Elevator Music.I enthusiastically told my sons that teachers have given this CD praise, and my 9 year old (after groaning though a few songs) said, "Maybe those teachers have imaginary students!"Anyway, others may like it, and I would encourage you to try to hear clips BEFORE you buy. There are better multiplication CDs out there...ONE BIG PLUS! I appreciate the efforts of putting math and music together. Any way learning can be fun for someone is important.
