ISO Spanish Children's books to send on mission trip to Honduras.  It is a dental brigade that hosts dental clinics performing free services.  They go to rural areas and the clinics are hosted in schools.  As a thank you for hosting them they give the schools supplies.  We have collected a huge amount of used school supplies to send there.  However, spanish books are hard to come by. 

Does anyone have good books on their shelf I can request?  Are you willing to do a deal on multiple books?

Can anyone make a recommendation of something that might be useful for me to buy on amazon?

Can be children's books written in spanish for schools to use in a library. 

Can be workbooks or textbooks so long as there is a good amount of spanish in book (I'm not sure how good their English is so if the instructions are mostly in English might not be useful for them?)
