Robin Butler Smith, 51, a Delaware County public school teacher, died of pancreatic cancer June 11 at her home in Sharon Hill.

Born in Washington, D.C, Mrs. Smith graduated from St. Joseph Academy in McSherrystown, Pa., in 1976 and earned her bachelor's degree with honors in elementary education from West Chester State College in 1980.

From then until November, Mrs. Smith taught third grade at Media Elementary School, where she coordinated the social-studies curriculum, said her mother, Frances Butler.

For the Rose Tree Media School District last year, Mrs. Smith wrote a supplemental curriculum for third graders, "Working With Words: Phonics Beyond the Basics."

She led a districtwide summer-school program for children with reading difficulties for more than a dozen years, her mother said, and was a member of a districtwide minority teacher advisory committee.

At St. George St. Barnabas Episcopal Church in West Philadelphia, Mrs. Smith directed the youth choir, coordinated church school activities, and for the last 13 years wrote and directed the children's Christmas and Easter pageants.

She was a member of the church vestry for several four-year terms, her mother said, and served on diocesan committees, mainly those dealing with youth.

Besides her mother, Mrs. Smith is survived by sons Carl and Ryan, a sister, and her former husband, Keith.

A viewing is set for 9:30 a.m. tomorrow at St. George St. Barnabas Episcopal Church, 520 S. 61st St., followed by an 11 a.m. Requiem Mass there. Burial will be in Fernwood Cemetery, Lansdowne.
