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.
My older daughter continued to draw; she especially drew mandalas and other geometric types of pictures. I was proud of her endeavors for they were truly beautiful. Years passed and any thought of coloring was far from my mind, then after my third daughter was born, coloring resurfaced. I was still too deeply entrenched in the line between childhood and adulthood that I resisted the draw of the crayons.
Apart from giving your kids a creative way of remaining engaged and passing free time, these coloring pages have quite a few other advantages. They are, for one thing, free to download and print, hence all you need is a computer, an internet connection, and a printer.
