Teach students (even young kids) the 20/20/20 rule: every 20 minutes, students should focus their eyes on an object 20 feet away for 20 seconds to protect their vision and create healthy habits.

  • Schedule stretch breaks to encourage sustainable ergonomics.
    • For example, you can also have students do a 2 minute dance-break in your class every 20 minutes.

  • This is important for helping develop the whole student to build an internal clock to take frequent breaks.
