In choosing a worksheet, it is important to review the source and check the material. Ensure that the material and answers are accurate. Evaluate the worksheet by completing it yourself. The worksheet should provide information clearly and accurately. Make sure it is exactly what you need to homeschool your child.
For example, if you are using a simple addition and subtraction worksheet with your child, draw or type up another sheet of with squares and numbers printed onto them. Instead of writing the answers to the questions on the worksheet you can get your child to cut and paste the required numbers for the answers from from the second worksheet onto the first.
