The advantages of coloring pages:
1) Self expression - coloring on a blank "canvas" (paper), is a method for kids and adults 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 necessary to offer kids an opportunity to express themselves, and not all kids express themselves through words and through writing, lots of use art.
2) Color recognition
3) Therapy - for many individuals (myself included) coloring is therapeutic. Regardless of whether it's scribbling, or coloring the "best image ever", coloring can be a method to de-stress, after a hectic morning of school work, wind down, and calm down, after the tensions 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 start to be established while coloring.
6) Structure motor abilities
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 kids learn from coloring pages, with preprinted photos on them, is how to accept borders. While a toddler or preschooler might scribble all over a coloring sheet, without any regard for the borders (lines on the coloring page), as the kid gets older, they will start to appreciate those lines, and make an effort to color between them. While I motivate blank paper coloring free of charge expression as typically as possible, for lots of young children pre-printed coloring pages are their very first direct exposure to printed borders. This early direct exposure to borders in print, will be a huge help when handwriting time occurs, and the kid has to appreciate the borders of the preprinted handwriting lines on the paper.
9) Milestone - This is the last little "significance" of coloring that I will mention in the meantime, and that is that coloring in the lines is a milestone, a sense of accomplishment, the primary step towards a successful academic career for lots of kids. For lots of kids coloring in the lines is simply as essential as counting to 10, counting to 100, reciting the alphabet, finding out the reproduction facts, etc. It's a milestone that states "yes I can" do whatever I encounter, and it provides kids with pride, a sense of self worth, and helps them to feel accepted in a society that is typically quick to judge, and slow to react. This sense of accomplishment will bring them through life, and help them not to quit so easily, when something new occurs.
