After completing her degree, Ragsdale taught in
New York City and Dr. Sach's School for Girls until 1905. She was head of the Baldwin School in Bryn Mawr from 1906 to 1911, and a reader for Charlotte Scott from 1908 to 1910. Ragsdale returned to
North Carolina in 1911 to accept a mathematics position at Woman's College in Greensboro (now known as the
University of North Carolina at Greensboro). She remained there for almost two decades and served as department head from 1926 to 1928. She encouraged the school to buy a telescope, and the math department to add statistics to the curriculum. In 1928, she retired from teaching in order to care for her mother's health and help manage the family farm. After the death of her mother in 1934, she built a house at
Guilford College, where she spent her last years gardening, working with furniture, working on family
genealogy, holding book clubs, and visiting with students. Upon her death, she donated her house to Guilford College, where it housed the faculty, alumni, and visitors. In 1965 President of Guilford Grimsley Hobbs moved into Ragsdale's house, and it has been the home of the college's president ever since. ==See also==
