Colorincolorado.org is an excellent resource for Spanish-speaking families and teachers of English Language Learners. It has a wealth of articles, resources, guides, etc. for parents and for teachers to communicate with Spanish-speaking parents. It was created/funded by the American Federation of Teachers and has the most up-to-date research on reading instruction for ELLs. I often go to this website first if I need to find Spanish articles on testing, reading as a family, etc. to send home to my families. Everything is in English and in Spanish.
