The advantages of coloring pages:
1) Self expression - coloring on a blank "canvas" (paper), is a method for children and grownups alike to express themselves. You can inform a lot about the way an individual is feeling by the images that they draw, the colors that they use, etc. It is very important to provide children an opportunity to express themselves, and not all children express themselves through words and through writing, lots of use art.
2) Color recognition
3) Therapy - for many people (myself included) coloring is restorative. Despite whether it's scribbling, or coloring the "best image ever", coloring can be a method to de-stress, after a hectic early morning of school work, wind down, and cool down, after the stresses of a day at school or work.
4) Grip/Control - lots of children discover how to hold a pencil, pen, marker, or colored pencil, by very first knowing how to hold a crayon. The small muscles required for penmanship later on begin to be established while coloring.
6) Structure motor skills
7) Focus - Taking notice of a single job for a length of time is required for coloring and for all sorts of things throughout one's life.
8) Borders - Another thing that children gain from coloring pages, with preprinted images on them, is how to accept limits. While a toddler or young child may doodle all over a coloring sheet, without any regard 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 in between them. While I encourage blank paper coloring free of charge expression as often as possible, for lots of preschoolers pre-printed coloring pages are their very first exposure to printed limits. This early exposure to limits in print, will be a huge aid when handwriting time comes around, 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 mention for now, which is that coloring in the lines is a milestone, a sense of achievement, the primary step towards a successful scholastic career for lots of children. For lots of children coloring in the lines is simply as crucial as counting to 10, counting to 100, reciting the alphabet, learning the multiplication facts, etc. It's a milestone that states "yes I can" do whatever I come across, and it offers children with pride, a sense of self worth, and helps them to feel accepted in a society that is often fast to judge, and slow to react. This sense of achievement will bring them through life, and assist them not to quit so quickly, when something brand-new occurs.
