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.
Many parents already know that coloring pages help develop their children's artistic abilities. They may not be familiar with the ways that using coloring pages can help their little ones to improve their skills towards writing. As children practice coloring, their abilities to stay within the lines improve over time. This focused ability to control the pencils or crayons precisely is an important part of being able to hold a writing instrument still and steady for when it is time to draw the letters of the alphabet. Artistic abilities are cultivated and strengthened in children who do well at coloring pages. Besides this, they will find it easier to start writing their alphabet letters when the time for this comes.
