I work on behavior with littles, my son is also severe ADHD. I would suggest for now visual timers at school and at home with transitions, whether it be an actual timer with numbers or a plastic hour glass, it may help. Sometimes kids have those types of reactions during transitions because they can't vocalize that they weren't ready to move to the next thing. Timers would help ease him into it so like setting a 3 minute timer and saying ok next we're doing carpet time, and allowing him to ask for 1 more minute 2x's so in total 5 minutes. Also I agree about the teacher involving the whole class in clean up, brining more attention to the behavior never helps improve it.
Also that's supposed to say I work in behavior lol sorry
Also feel free to message me if you want :)
Thank you all for your advice i think the timer is a great idea as he is always asking for 5 more minutes whether its bath time,phone time or getting out of bed and asks to see my fingers so he knows how long he has left
I am a reception teacher and have taught many similar children. They should be able to put things in place to help him and support him and you. Are u in england? If so i would ask for a meeting with the sendco (special educational needs and disabilities coordinator) if you haven't already spoken to them. They need to tell you what they are referring him for before u go to the doctors. They should be able to put a plan in place which says exactly what the needs are, how they will meet them and set targets for him to meet. Things that usually help are visual time tables that set out exactly what is happening during the day so he knows what to expect, sensory breaks ie time out of the classroom or to run around outside as noisy, busy classrooms can be overwhelming, sand timers to show when they are moving on to a different task or for a task to be completed, being clear and firm with instructions.
Here if you need to talk I understand xx
