Hello, Helen. Greetings from Romania! Guess what! I have become a volunteer. I'm currently working at a school in Krayova city. My project was named "Bi Fit". The program is for 3 months. My main goal is to get children physically fit, and showing love for sports. It's amazing! In the morning I will be doing exercises with the children. Then I will teach Romanian classes afterwards. In the evening I and other volonteers will be playing other outdoor games with the children. I will have to write some reports sometimes about my job. So far I'm really enjoing the job! You get the work experience. You have to be very patient, creative,and caring. Because you work with children every day. Why don't you apply for a project here too? That would be great! See you soon! Love, Marina.

Nice.  Remember your articles and prepositions (very necessary in English).  Also, in many cases, you could use the Present Perfect verb form for regular activities, rather than the Present Progressive.  Best wishes with your volunteer placement.
