Studying the same subject together as a family, unit studies, has many advantages. It is much easier for mother to teach just one topic, rather than trying to explain several different subjects to several different children each day. The whole family can enjoy discussions together on the same subject. Enrichment activities such as movies, art projects, or field trips on the subject apply to every member of the family. I have found teaching all my children the same subject together has been a most rewarding experience!
