There are other sources for worksheets also. You can find many public schools and private schools which will provide free worksheets for you if you buy textbooks from the school. Or you can usually find textbooks and workbooks at the public library, where you can also copy any worksheets that you want to use.
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.
