Choose an area in your home where your child will study.
Limit distractions during this time such as TV or music with lyrics.
Using this mail slot for my son has helped with getting the assignment out of the door in the morning and with him on the way to school.

We placed it so that it is very close to being the first thing he sees coming in and the last thing he sees going out.
The geometry may be a bit challenging in your house but even if you can’t get ‘optimum placement’ such a central place for him will be very helpful.

My son and I tried Mozart and other classical music, and some different types of jazz.
