Absolutely!
I teach a few of them.
I'm sure you are and excellent teacher. I just ask that you be cognizant that even though they may exhibit some of the behaviors does not mean they are ADHD. Never under ANY circumstances suggest to the child they are somehow defective or have some problem the other children do not. This will destroy the child's confidence and lead to a downward spiral of behavior that will make your job as a teacher that much harder. I've seen it and was powerless as a parent to fix it and was quite angry with the teacher.
Inability to pay attention to a boring subject is a discipline problem not a ADHD problem. ADHD children cannot pay attention to any subject. interested or not. Make your lessons interesting if you teach the younger grades. The older children should have developed the discipline necessary to perform menial boring tasks already.
This is a sensitive subject for me because I lived it and refused to drug my child with anti-psycotic drugs. In my opinion the cure is worse than the disease in most cases. More stringent discipline and cooperation with parents is critical for these children. It must be done in a way as to not make the child feel singled out. Young children pick up on "fairness" much faster than adults and they do not understand life is not fair, nor should they have to at a young age.
This is no surprise to me. I’m 56, and I was diagnosed four years ago—Oh! Look! That dog has a puffy tail!
