I had a few good discussion about 9/11 today with my students. I was impressed by how informed they were, which is pretty cool because it means that either their parents/family members have talked to them about it or they heard it from their other teachers over the years.
I remember that about a year after the attack the governement was offering free DVDs that would help parents explain what happened to their children. I ordered one but never received it. It is unbelievable that it has been 17 years but the images in my mind seem like it just happened.
