There may be many fun games for kids over internet but coloring pages from Disney story books have no substitute. They can be provided by school teachers as a fun activity too. But you also need to award your child when he is done with the coloring. Kids need appreciation and it can be done by encouraging them through rewards.
The theme: Coloring books generally have a theme of sorts. It might be that they are based on a Disney movie, or it is about animals, or vehicles, or something else. When selecting books for your children, remember that they will want to express their creativity, and will have a lot of fun with any coloring book, but will be more interested in a coloring booklet with a theme that appeals to them. Choose a color book that features their favorite characters, or the item of interest in their life. For example, if your little boy just loves trains, get a Thomas the Train coloring book. If your little girl is as girly as they come, look for the Disney Princess coloring book, or possibly Strawberry Shortcake.
All the reasons listed above prove that coloring pages is a great educational tool for children.
