A new program started by two teachers in Spokane, Wash., schools aims to improve learning among kindergarten students by integrating physical activity into lessons in basic reading and math skills. In one recent lesson, students read words aloud before hopping over them, and pronounced letter sounds while stepping on colored buckets. "We really want kids to be able to read by the end of kindergarten," elementary-school literacy coach Kari Cunningham said. "Knowing their letters and other sounds are those foundational pieces. We want them to be prepared for the first grade."
