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.
So the next time you do a search for curriculum materials, skip the worksheets. Instead, consider resources that provide interactive experiences or consider sites that provide students with challenging problems. These sites will more likely engage students, foster discussion, and build a true understanding of the purpose and joy of learning math.
