Care should be taken to give children worksheets that they are capable of doing. This involves understanding and monitoring the child continually, since the level of attainment of different children would often be quite different. The worksheet should challenge the child but not overwhelm her. If the worksheet is too easy or too repetitive, it may bore the child and she would not be happy. If the activity is too difficult it would frustrate her and she would not like to take up more sheets. The children should love to do the worksheets; they should not be thrust upon them. Also doing only worksheets alone repeatedly would not be very productive. You should have a range of physical games and activities as well that would reinforce the concepts learnt.
Pleasant and Attractive, Using current word processing programs and computers allow worksheets to be created using colorful graphics that children will find very enticing. This makes them more comfortable and relaxed the worksheet can look more like a game than a test. Using this colorful format, kids are able to feel eager to learn. The most exciting part is now they are developing online worksheets that have animated graphics. These can be access on a website from anywhere they have computer access which makes it an attractive solution to entertain your child while learning.
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.
