As already mentioned free coloring pages are a great way to teach your child all sorts of things, numbers for example. There are different ways this can be done, one way would be to simply have the number somewhere on the page, such as the number 10, and then somewhere else on the page would be an object or animal cleverly twisted into that number. There could also simply be 10 of something on the page, you can get your child to color the page in and then count out how many apples for example there are, which will obviously correspond to the number on the page.
Finally, children who are involved in coloring pages will most likely experience fewer psychological problems when they are young. The reason for this is that the minds of children, who are able to enjoy using their imaginations to create exciting worlds filled with fantasy and adventure, are strong and flexible. This coloring creativity aids them in steering clear of problems like childhood depression.
