After perusing, I find the books to be very teacher friendly, even for the teacher who knows or speaks very little Spanish.  I must note that the content is closely aligned to the curriculum of the Ministry of Education and the illustrations are visually stimulating for students. Furthermore, many of the illustrations are culturally relevant. I am very pleased with the glossary at the back of the books, which offers the proper pronunciation of words. In light of the above, I highly recommend that teachers employ these books in their Spanish curriculum.
