Do you think it is important for teachers to learn at least one new language?

Solution #1
I think it makes for an excellent tool, and that it's weight carries importance, however I don't feel that it is mandatory or required that they learn the new language. Having the skills to educate ELLs is more important.
Solution #2
I speak English and Spanish and it has helped me out as an educator tremendously and I feel that all teachers should at least try to learn another language to better communicate with their students
Solution #3
Depending on the area where you're teaching this can be really beneficial (with it almost certainly benefiting the class no matter what), but regardless it is for sure a good skill to have whether you are a teacher or not.
