Common Core 5th Grade ELA Question of the Day

Many students arrive at first period yawning, but starting school later could help. Sleep researchers explain that preteens and teens naturally fall asleep later because of changes in their bodies. In a pilot program at Westview Middle School, classes began at 8:45 a.m. instead of 8:00. After two months, students reported an average of 34 more minutes of sleep per night, and the school recorded 12 percent fewer tardies. Teachers also noticed more students participating in morning discussions. Some worry sports and jobs would be harder to schedule, yet the district tested adjusted bus routes and moved one team's practices to afternoons during the trial. The author's point is that a later start improves student health and learning.
