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.
Linking by creating a formula. With this method you can create an inter_active link between worksheets or workbooks. The linked cells do not need to be in the same location on all worksheets. You can perform any math operation while creating the link. For example, you could take a figure from one worksheet, multiply it times a figure form another worksheet and then subtract a number from a third worksheet. You can use this method to link cells across worksheets or workbooks. One disadvantage of this method is that it is time consuming because you are working with one cell at a time. Using named ranges can assist with this method of linking and make it easier to read your formulas once they are created.
