Buddy is easily distracted by his friends and he misses the morning bell; this is explained by his challenges with orienting because he can't orient to the right cue.
*chatter*
That's the bell! We're going to be late, Buddy!
When Buddy gets inside, his locker is disorganized and he can't find his pencil case; Buddy's disorganization causes him to forget what materials he needs for class.
I saw a really cool snowman, I should go back and look!
Buddy may have difficulty getting his materials ready for class because he struggles with transitioning or set-shifting; he just came into school but is still thinking about snow outside!
Buddy! You're late to class!
Buddy doesn't have his materials ready because he has troubles with planning, and because he's not ready, his teacher is upset with him.
Buddy can't sit still because he has poor inhibitory control; he can't help his impulse to talk to his friends, even though the teacher is speaking and the class is upset!
Buddy brought the wrong work to his morning class; he needs his math workbook but he brought his social studies work instead; this can be explained by Buddy's planning and organization challenges.
