If things are scattered, arrange them in an order, for ex: make a routine for the child and divide time slots accordingly. Give them a variety of activities so that they don't get bored with one and they look forward for each one of them. If you set up a routine for your child to follow, she can clearly focus on her goals and give her full concentration to completing them. Let them do their homework only at the study table, drawing or painting in the art room, etc. This will build their association with that activity and especially those activities that they are supposed to do daily. Give them light snacks and meals that are nutritious and give her the energy to concentrate. Keep the environment clean and tidy. The more chaotic the place is the more the distraction, it increases stress and decreases the ability to pay attention.
