Know the author's background. This person needs to have a background in education and, ideally, should be trained in the latest educational methods, like brain_based teaching/learning. I personally would never use any materials with my child that didn't specifically mention being "brain_based." I am not talking about just "research_based." I see more and more sites claiming to have research_based materials, but what I find is definitely NOT based on how the brains actually learns. Brain_based learning is relatively new in the educational world, but most worksheet sites and materials are using old science or, more often, no science at all.
How many Worksheets can I Create within one Workbook? _ Prior to the release of Excel 2007 users could only create 255 within one workbook. However, since the release of Excel 2007 users can now create as many worksheets within one workbook as the memory of the computer can handle. Even if the user does not have access to one of the newest versions of Excel such as Excel 2007 or Excel 2010, they can still make as many worksheets as they would like, but earlier versions of Excel will require more workbooks.
