Yesterday I got a new student who speaks no English -- zip, nothing, nada, no "hello," no "bathroom," nothing. I paired him up with another ELL who came in knowing next to no English (well, except for maybe "bathroom") but who is now on her way to being a D reader and who is a regular English chatterbox! (I love love love how quickly some beginner ELLs make progress!)
During reading time I overheard another student telling her to explain something to my newcomer in Spanish. She gave the suggester a total "duh, girlfriend" look and said, "No, he needs to learn English. No Spanish. Talk English!"
