I am not Hispanic but it doesn't seem to be an issue with the parents. They really haven't asked me! I have a Spanish last name (Garcia) and still have my Castillian Spanish accent when I speak, so maybe they think I'm from Spain!
I did live there for over twelve years.
I will be checking out the textbooks you've recommended. I'm still waiting to hear from the administration and school board if this class has been given the go-ahead for next year.
Thank you all for your comments and suggestions!
