No-Sew Pillowcase Chair Pockets...have the students put all of their stuff from their backpack in these in the morning & and ad stuff to it throughout the day that needs to go home, then at the end of the day whatever is in their pocket goes in their backpack this way they are not running to their backpacks allll day.
A homework desk and friendly routine can work wonders for adhd distracted or scattered kids. Set a timer (10 minutes/grade level - 2nd graders work for 20 minutes). When the timer goes off - put away the books, no matter if some things are left undone. Small extensions are okay if the student is in good spirits and wants to continue working.
