While coloring pages may seem simple in the minds of parents and other adults these days, they are often the passport into a more creative style of play. Yes, your child will simply color the picture online, but by doing so, she is learning not only to stay inside the lines, but to balance color and texture and to simply use her imagination. If a coloring page for kids is the first step into a full-fledged imagination based entertainment package, it is unlikely many parents will find them simple for long.
Another benefit has already been discussed above, that kids enjoy colorful learning and they love such fun loving methods.Besides you can get multiple copies. That is because kids do have habit of destroying things specially the books and papers. If they tear apart one page, you can have another ready immediately for him/her. And everything is in digital format, thus you can store some pages in your computer too and get them printed when you need one.
