From a teachers perspective our competition is tough. Passing out a handout of 30 problems that are all in a format of 534x25= is not as stimulating in the students eyes as playing games such as Grand Theft Auto and Resident Evil. Granted, that will always be a tough uphill battle for math to win out over most video games, but the point is, students today are much more immersed in technology than ever before. So even if you need to pass out a math worksheet to review concepts and formulas, it will greatly benefit your cause if you design the worksheet to be as stimulating as possible.
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. Free homeschool worksheets that you can print are available online. Some of them may be excellent, but you will have to make sure that they are accurate and suitable for your curriculum or child.
