Coloring in is one of the main starting points of creativity in children. Being able to expressed ones self with a piece of paper and colored pencils or crayons is a great thing to be able to do and remember, it leads onto being able to learn other brand new skills. Quick tip! If your child has difficulty holding a colored pencil then try them with crayons first. Crayons are easier to hold because they are larger and softer. But as your childs skills and abilities progress they will prefer the greater accuracy of using colored pencils.
You can metaphorically take a page out of a coloring book, and break up the work into a few sections. Each team member or group within the team should first be instructed on which part of the page they are going to color, let them know what color they can use, and when their turn will come up. Next, after each team member has finished their part of the coloring than take the completed picture and hangs it up so that every one can see their part of the picture and the entire teams contribution.
