For example, if you are using a simple addition and subtraction worksheet with your child, draw or type up another sheet of with squares and numbers printed onto them. Instead of writing the answers to the questions on the worksheet you can get your child to cut and paste the required numbers for the answers from from the second worksheet onto the first.
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.
