How does Excel store Worksheets? _ Worksheets are saved in an Excel file called a workbook. These workbooks are what Excel uses to collectively organize all the different related parts of many different related worksheets as well as the related charts, graphs and various other objects within Excel.
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.
