If while coloring your child goes out of the outline, it will not be so noticeable. When the child sees how cool his result is, it will inspire confidence in him and will be a good stimulus for further work. Good coloring are those with the text in it. The text introduces the kid with the game, the kid will be interesting, while the text will expand its horizons.
Coloring pencils or markers are useful for the development of fine motor skills. After painting the small objects, the child learns not to go beyond the boundaries of the drawing and trace the thin lines.
