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 what you are buying. If you can't see it (there is no sample shown), then do not buy it. There are many people out there trying to make a buck off the current popularity of worksheets. Many, if not most, of these people know nothing about mathematics, teaching, or how the brain learns. Anyone can type columns of addition, subtraction, multiplication, etc. problems; but these worksheets will be bad for your child. Don't trust what you can't see.
