This will help them to not only recognize different colors but to also learn the names of the different colors. Developing these skills will help in later development too as your child begins to learn to read and write. He or she can then learn how to write the names of all of the different colors. You see learning is progressive and incremental - it happens in stages. Step-by-step as I have described. This is the true beauty of learning...the more that your child puts in, the more they will get out of learning. As their knowledge grows, so will their interest in a range of different subjects.
Coloring in a Doodle Book. You can do this very effectively by getting an artists sketch pad. This is a pad of blank sheets of paper used by artists to plan their paintings or creative work on, much like a writers rough draft. Once you have your pad, take a pencil and start to doodle. Make lines, circles, shapes, what ever at the time makes you feel good. Then color in the spaces within the doodles. Even if you think you are not a very creative person you will feel productive and relaxed after a few doodle your noodle calming sessions.
I was picking out some coloring books for my friends children when she informed me that she would like to get a couple of books too. This is a 30 something year old woman. She then began picking out colored pencils as well with a gleam in her eye like a kid in a candy store. She couldnt wait to get home and start coloring in her new books. She picked Barbie Doll, princess type books and methodically chose what colors she would use for the first picture.
