MISSOULA, Mont. - Some special volunteers are returning to the classroom after having to find new ways to help out from afar for the last year. Foster Grandparents is a Missoula Aging Services program. They play an important role in Missoula schools. They're placed in different classrooms and help teachers by providing students with more one-on-one attention. One foster grandparent heading back to school is Orrin Johnson. To his second graders, he's known as Grandpa J. Grandpa J is a busy man. As a foster grandparent, he serves as a crossing guard in the mornings, helps pack lunches at the food bank and also helps tutor at St. Joseph Elementary and Middle School in things like fifth grade math and second grade reading.Â
