Hi, my daughter had very strong difficulties with the times tables, so I bought two CDs and, to hear her asleep at night .... And after two weeks it was all not so hard. Prima. She also no longer as the pressure at school verspührt because she always quietly sang the song in your head. Of course it was a little slower than others can learn by heart and super can juggle figures, but, absolutely awesome for my mouse. She stands there on Hip Hop and loved it !! And I because you learn the easy times much and I have not heard gemaule. ;-) Conclusion: Great music; great lyrics and great learning experience !! English is the new CD that I ordered, .... ;-)) is very excited to have. Lg Katrin
