The advantages of coloring pages:
1) Self expression - coloring on a blank "canvas" (paper), is a way for kids and grownups alike to express themselves. You can inform a lot about the method a person is feeling by the images that they draw, the colors that they use, etc. It is essential to give kids an opportunity to express themselves, and not all kids express themselves through words and through writing, lots of usage art.
2) Color acknowledgment
3) Treatment - for lots of people (myself consisted of) coloring is therapeutic. Despite whether it's doodling, or coloring the "finest picture ever", coloring can be a way to de-stress, after a hectic early morning of school work, wind down, and calm down, after the stresses of a day at school or work.
4) Grip/Control - lots of kids learn how to hold a pencil, pen, marker, or colored pencil, by very first learning how to hold a crayon. The little muscles required for penmanship later on begin to be established while coloring.
6) Building motor skills
7) Focus - Focusing on a single task for a length of time is necessary for coloring and for all sorts of things throughout one's life.
8) Boundaries - Another thing that kids learn from coloring pages, with preprinted images on them, is how to accept limits. While a young child or young child may scribble all over a coloring sheet, without any respect for the limits (lines on the coloring page), as the kid gets older, they will begin to appreciate those lines, and make an effort to color between them. While I motivate blank paper coloring for free expression as often as possible, for lots of young children pre-printed coloring pages are their very first exposure to printed limits. This early exposure to limits in print, will be a big help when handwriting time occurs, and the kid has to appreciate the limits of the preprinted handwriting lines on the paper.
9) Milestone - This is the last little "importance" of coloring that I will point out for now, which is that coloring in the lines is a milestone, a sense of achievement, the first step towards a successful academic profession for lots of kids. For lots of kids coloring in the lines is simply as crucial as counting to 10, counting to 100, reciting the alphabet, discovering the multiplication facts, and so forth. It's a milestone that states "yes I can" do whatever I discover, and it offers kids with pride, a sense of self worth, and assists them to feel accepted in a society that is often fast to judge, and slow to respond. This sense of achievement will carry them through life, and assist them not to give up so easily, when something brand-new comes along.
