Children at Lincoln County's Midway Elementary take a mid-morning walk on the school's new trail, "to stir their brain cells," principal Cheryl Workman said in May. "Superintendent Marple would be proud of us."

Fifth-graders at Webster County's Diana Elementary weave physical activity breaks between science and language arts lessons, as part of the Marple-inspired effort to get kids moving through the day.

At Calhoun High School's school-based health center, nurse practitioner Lisa Coleman treats students on-site, with parents' permission. Under Marple, the number of centers jumped from 58 to 75.
