What if the vocabulary words in the Spanish translation are not appropriate for the students I teach?

This will happen. Especially at the preschool level, there are many regional variations for the same object or animal. If you feel another word would be more appropriate for the Spanish speakers in your class you may use it.

Be sure, however, to use the same word selection for all the Spanish speakers in your class. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
