@boneghazi Attend to the sensory pieces. Find out what he needs in order to focus as well as he can, and give him that to the greatest extent possible. Anecdote: In kindergarten one of my kids was accused of being deliberately inattentive (I don't know what the actual fuck that means), and so during a parent-teacher conference where the teacher was trying to demonstrate that he wouldn't pay attention even when she was speaking directly to him, I spoke with her in a much quieter tone of voice than she was using... and as I was speaking, I slowly removed everything from the table between her and us. As soon as the table was free of objects, my kid looked up and started watching the conversation between us, particularly my half, until the teacher dropped her voice to a lower volume, and then he started looking at her, too. I have learned over time that he learns best:
- in a visually uncluttered environment,
- with a quieter volume than we use for typical conversation, much less kindergarten-teacher-boss-voice,
- with some kind of physical touch sensory input (snuggled up to me works pretty well)
and additionally he melts down when hungry (ADHD is not his only diagnosis), and his school had his lunch scheduled criminally early (9:45am! with 5 more hours of school to go!), so I had them giving him a (nut-free) snack in the afternoon.
Basically, this is the last step of HALTS (hungry, angry, lonely, tired, sensory) - once you're sure focus isn't being impaired by one of the first four, run through the senses and see if you notice attention focusing on less-prefered topics more when there's higher or lower inputs on any of them. I'm happy to talk with you more about this if you think it would help.
