These sites are easy to find on the internet and they provide the child with a chance to explore his creativity. He is all by himself to experiment and learn. The shapes and colors will keep him busy and his mind occupied in making the best use of colors and drawings. Once the drawings are printed he can take them along to his room or to some other part of the house that pleases him.
Check around at your local cheap shop for a 100 to 150 page coloring activity book and then carefully tear out the pages or cut them out. You will then see that this will give you one page with two pictures on it front and back. Get your child to pick through the pictures until they find one that they want to color in and let them go to it. When they have finished that picture turn it over and get them to color in the other side of the picture. This will keep them entertained for ages if they are tempted to just color one color then encourage them to make it more colorful because you something special planned for their picture once they have finished but they need to make it colorful.
All the reasons listed above prove that coloring pages is a great educational tool for children.
