Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. It not only benefits the people you help but will give you great experience of feeling what it is like helping somebody, you know giving is even happier than being given. A new community program called "One on One" helps elementary students who’ve fallen behind. You education majors might be especially interested in it because it offers the opportunity to do some teaching—that is, tutoring in math and English.
   You’d have to volunteer two hours a week for one semester. You can choose to help a child with math, English, or both. Half-hour lessons are fine, so you could do a half hour of each subject two days a week.
   Professor Ray will act as mentor to the tutors—he’ll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week.
   I’m sure you’ll enjoy this community service and you’ll gain valuable experience at the same time. It looks good on your resume, too—showing that you’ve had experience with children and that you care about your community. If you’d like to sign up, or if you have any questions, stop by Professor Ray’s office this week.
