My favourite idea would be to have Luis involved in extra curricular activities after school, for example a drama club. This would positively affect all areas of his well being. For instance, he would make friends as he would be in a group where children share common interests, and this would allow him an experience to enjoy, make friends, interact socially and be happy. 

As, well as, once made friends, a reminder to his parents or himself about the work to be completed for the day can be given by his friends, alleviating the fear he has of getting into trouble for forgetting the task to be done.

the activities at the drama club would also develop his motor skills and movement. he would develop holistically once in this club
