My sister posted a wonderful video on her blog about 9/11. I'm going to ask you to follow the link to her blog.
As an aside, we must remind our young children what 9/11 is. My students are juniors and seniors meaning they were only in second or third grade when this happened. Many don't seem to understand the true significance of this event. We must never let our children forget!
