In a neighborhood parade led by kindergartners, Washington Elementary School's 582 students wear their school colors of red, white and blue Monday to open their yearlong celebration of the school's 100th birthday. Opening its doors as Washington Elementary on Sept. 12, 1892, the school was originally the 17th LDS Ward school. The school, 420 N. 200 West, was named for the nation's first president; a bust of George Washington sits in the school library. Washington is the district's second oldest elementary school. Lowell Elementary celebrated its 100th birthday last spring. In a rare collaboration including the U., Washington Elementary is the site of a two-year program to train teachers about better mathematical concepts and instructional methods. Summer training focused on teaching number systems, fractions, geometry and estimation.
