Here are some thoughts that might be helpful as you support your students in the aftermath of the shooting in Colorado. These events are still extremely rare.

We all need to work on creating a school in which all kids feel they belong in some way. Teach all youth leadership skills, and have the leadership of each group move to a new person each week. Another way to gain recognition for those students who are often in the background. Giving students ownership of the solutions brings much better results. Celebrating events that represent the many cultures in a given district.
