My kid HATED 1-2-3 Magic, and it escalated his anxiety tremendously, creating new problems instead of solving them. I would be wary of using it with an AS kid.

If they are having behavior problems, I would insist on their doing a functional behavior analysis (you should probably request it in writing). This involves their taking data on each behavior incident: what was going on when it happened, what the child did, and what the consequences were. Having each event documented allows you to see patterns: does it only happen during math? Does the child use behavior to escape a boring classroom? Once you pinpoint how the child is using the behavior, you can design a solution with the team.

Best,
