Rice graduated from Oberlin College in 1900, and earned a master's degree at Western Reserve University in 1909.

She was professor of mathematics and astronomy and head of the mathematics department at Milwaukee-Downer College in Wisconsin from 1925 to 1947. She was an active member of the Mathematical Association of America. She traveled to Trujillo, Peru in 1936 to witness a total solar eclipse, and wrote about the trip and the event for the Oberlin Alumnae Magazine, quipping that "no subject under the sun is more worthy of study than the sun itself".
