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.
Children who have a strong and active imagination possess a powerful tool that will serve them well throughout their lives. Coloring books and coloring pages are a terrific tool for getting started in accomplishing this task. This is because such coloring pages develop and encourage the creativity lying latent in the child. Children are able to imagine how a picture might look in different color combinations, and this simple act has the power to create a strong and flexible mind.
