Get organized! Make sure your student has everything needed with which to do homework, study and projects.
Teachers may have different requirements for classes. Make sure your student knows the difference and has the proper materials.
Extra binder paper, pens, and pencils are important.
Make sure your student has times when to do homework. A quiet study area is important. The kitchen table is not the best place for doing and learning school work. If the student needs supervision, find a place where checking with the student is easy but out of the way of the flow of other household activities.
