While worksheets for homeschool can assist in home schooling, they cannot take the place of a proper homeschool curriculum. One disadvantage they have is that they often focus on one subject area only, without integrating the whole curriculum. They can also be simplistic and give the impression that the student understands more than he actually does.
It is a lot easier to teach your child or to help them with school homework if they have had experience of learning in the home. Very often moms teach their children a lot of skills without actually realising that the fun they are having is a great way for a child to learn.
