The 29 letters covered include "ll", "n~" and "rr", as well as "w" which a note explains is not actually needed for Spanish, but used for foriegn words, such as William.
Probably works in English too, and the English translation is provided on the right-hand side of each page. I rate it 9 out of 10 because of the simplicity of the art- not stylish, just simple. Paper or felt cut-outs. The text is a 10. Recomended!
A great way to develop new vocabulary and concepts while having fun!
