Quality vs Quantity,Some free worksheets are not good quality - the pictures are fuzzy, backgrounds print grey or speckled - and children tend to notice these things. If you are using the worksheets to educate your child, you may want to choose good quality worksheets that encourage your child to produce good quality work. After all, its a little difficult to ask your child to color within the lines and work neatly when the worksheet they are filling in hasnt done the same.
To Pay or Not to Pay? There are hundreds if not thousands of free printable worksheets available online. These are ideal for filling time or keeping the kids busy on a rainy day, but few of them offer a systematic set of worksheets with activities designed to teach your children a specific set of skills. If education is your aim, you may have to spend a little to get useful, comprehensive worksheets that actually help your child to learn.
