Challenger Elementary Kindergarten teacher Nancy Chen tends to a large and beautiful dahlia garden outside the school. Recently, some of that beauty came inside. Chen and special education teacher Jill Holbrook started the Dahlia Project: Holbrook's third- through fifth-grade students paired with Chen's kindergartners to select dahlias from the garden and deliver them together to classrooms throughout the building. The students got the chance to meet new friends and work together, and the school got a lovely splash of color.
