The benefits of coloring pages:
1) Self expression - coloring on a blank "canvas" (piece of paper), is a way for kids and grownups alike to express themselves. You can tell a lot about the way an individual is feeling by the images that they draw, the colors that they utilize, and so on. It is important to give kids a chance to express themselves, and not all kids express themselves through words and through writing, lots of usage art.
2) Color recognition
3) Therapy - for many people (myself consisted of) coloring is therapeutic. No matter whether it's doodling, or coloring the "finest picture ever", coloring can be a way to de-stress, after a hectic morning of school work, wind down, and relax, 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 first knowing 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 - Focusing on a single task for a length of time is required for coloring and for all sorts of things throughout one's life.
8) Borders - Another thing that kids learn from coloring pages, with preprinted photos on them, is how to accept boundaries. While a toddler or preschooler might scribble all over a coloring sheet, with no regard for the boundaries (lines on the coloring page), as the kid grows older, they will start to respect 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 preschoolers pre-printed coloring pages are their first direct exposure to printed boundaries. This early direct exposure to boundaries in print, will be a huge help when handwriting time comes around, and the kid needs 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 lots of kids. For lots of kids coloring in the lines is just as essential as counting to 10, counting to 100, reciting the alphabet, learning the reproduction facts, etc. It's a milestone that states "yes I can" do whatever I come across, 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 respond. This sense of accomplishment will bring them through life, and assist them not to quit so easily, when something new occurs.
