I volunteer at one of the Boys and Girls Clubs in the city where I work. I help the kids with homework and then we usually play games and sports after the homework is completed. Many of the kids speak Spanish as their first language, and even though they go to English speaking schools they have not mastered the language yet.
We sometimes have problems communicating with one another, but even though I don't know much Spanish and they are not fluent in English we manage to figure it out somehow. However, I know the school work would be much easier for many of the Spanish speaking kids if they had a better grasp of the English language.
I try to do everything I can to help them learn English. However, English is one of the most difficult languages to get a feel for, so hopefully they get better as they go along in school and as they interact with other kids who are speaking English.
