Hi. So there is a 4yo Pre-K boy in my class who has struggled from day one. He's just had a hard time adjusting to the structure and I really feel like he's got something more going on attention-wise (I suspect ADD/ADHD). I know it may seem controversial to jump to that conclusion, but I feel like I see the signs the more I observe him. He struggles to sit still even for a short amount of time, he's very defiant at times, and will often interrupt and even shout out sometimes. The thing that makes me wonder if it is ADD/ADHD is that I don't think he can control it. What I'm wondering is what kind of behavior plan I can implement. I'm wondering if a simple sticker chart will work. Has anyone tried this with a child this age? What kind of reward/incentive do you offer with it? Also, if it turns out that he can't control his behavior, will the sticker chart even work? He has to be able to control himself to earn the sticker, but what if he really can't? I'm trying to look for positive behavior reinforcement rather than taking free time or recess time away. Any words of wisdom?? Thanks!
