The benefits of coloring pages:
1) Self expression - coloring on a blank "canvas" (piece of paper), is a way for children and grownups alike to express themselves. You can inform a lot about the way a person is feeling by the images that they draw, the colors that they use, etc. It is necessary to offer children a chance to express themselves, and not all children express themselves through words and through writing, many usage art.
2) Color acknowledgment
3) Treatment - for many individuals (myself consisted of) coloring is healing. No matter whether it's scribbling, or coloring the "best picture ever", coloring can be a way to de-stress, after a hectic morning of school work, unwind, and relax, after the tensions of a day at school or work.
4) Grip/Control - many children find out how to hold a pencil, pen, marker, or colored pencil, by first learning how to hold a crayon. The little muscles needed for penmanship later on start to be developed while coloring.
6) Structure motor skills
7) Focus - Taking notice of a single task for a length of time is necessary for coloring and for all sorts of things throughout one's life.
8) Limits - Another thing that children learn from coloring pages, with preprinted images on them, is how to accept boundaries. While a toddler or young child might scribble all over a coloring sheet, with no regard for the boundaries (lines on the coloring page), as the child ages, they will start to respect those lines, and make an effort to color between them. While I encourage blank paper coloring totally free expression as often as possible, for many young children pre-printed coloring pages are their first exposure to printed boundaries. This early exposure to boundaries in print, will be a substantial help when handwriting time happens, and the child has to respect the boundaries of the preprinted handwriting lines on the paper.
9) Milestone - This is the last little "significance" of coloring that I will discuss for now, and that is that coloring in the lines is a milestone, a sense of accomplishment, the initial step towards an effective scholastic career for many children. For many children coloring in the lines is just as essential as counting to 10, counting to 100, reciting the alphabet, learning the reproduction realities, etc. It's a milestone that says "yes I can" do whatever I encounter, and it offers children with pride, a sense of self worth, and helps them to feel accepted in a society that is often quick to judge, and slow to respond. This sense of accomplishment will carry them through life, and assist them not to quit so easily, when something brand-new occurs.
