There are a number of really great articles about ADHD here at SchoolFamily.com. You can see a list of them at: https://www.schoolfamily.com/school-family-articles/category/683-ADHD-and-ADD?limit=all Essentially, imagine that you are distracted by everything around you while you are trying to work. Noises, music, pictures, lights, color.....Create an environment that is as free from these distractions as you can. You need to especially make sure she is not distracted by television, the computer, or her cell phone. These a major problems for all students! ADHD children need structure and routine, too. So, have her do homework in the same place at the same time each day.
I am not sure eliminating all distractions is the answer. No one can eliminate all distractions and the littlest things can distract an ADHD person like a cut on their fingers, their cuticles, the hair on their arms etc. Sometimes putting headphones on with soothing music can help the person concentrate. Chunking material can help i. e. work for 15 miutes break perhaps with exercise or relaxation etc. Discussing what works for tthem and having the child plan out their program can be very effective.
