Casio Label

I need help, I'm trying to label this music keyboard Casio CTK-480 is and has 36 white keys?

I have to lable for a beginner who wants to learn.

The Black Keys are in groups of two and three, the (A) in any set of three, between 2nd and 3rd key. Then goes right along the next targets are the keys B, C, D, E, F, G. repeat A, B, etc. Any white keys on the left of its initial (A) obviously run backwards! The black keys are the flat and sharp objects. I hope that all makes sense! I'm just going by what is on the keyboard of my daughter.
