I know researches recommend having larger paper to draw on as opposed to the smaller ones. They argue that the larger the paper, the larger the child’s imagination. So, since they are saying larger is better, they recommend walls and floors. (like maybe huge sheets of paper on walls or writing on the sidewalk)
Also, the larger the paper, the more the child’s arm is in motion. In stead of just the fingers moving, so does the wrist. And if on even bigger paper, so does the elbow. And on even bigger paper, so does the shoulder. Each joint of the arm offers a different radius of coverage on paper, which translates to offering more possibilities of creation on paper. Does that make sense?
I know in Japan, every toy store had this cardboard house or vehicle for sale. It came in the basic shape of the house or vehicle with outlines for windows, doors, etc. But the kids were free to draw on the cardboard as they liked. I don’t know if they have it here in the states. It was a huge hit, but something you could do at home, too, you know? You could combine a few boxes and make it look like robots, fire trucks, whatever your child likes, and enjoy drawing the people and tools, etc. It is fun!
(This doesn’t have much to do with drawing, but also popular was the use of empty milk or juice cartons to make bricks to create animals, giraffes, play houses, vending machines, everything!)
I have a three-year-old daughter who still benifits from coloring IN the coloring books (well, within the lines anyway), but I also heard there are many people against regular coloring books. (After a certain age/stage, I think,) they feel that kids should not simply color IN, but actually learn to draw. I forgot what they called those coloring books. Maybe something like the UNcoloring book, but I cant’ be too sure.
Don’t forget to encourage your child to use both hands to draw (if you’re not against using the left hand for drawing)! It’s a good way to encourage even more brain synapses. Start early before they start to prefer one hand over the other! (I do the same for chopsticks, too.)
My daughter and I like to talk about mixing colors, like making the rainbow with only red, yellow, and blue. She seems to get it. We talk about putitng yellow apple juice in a blue cup to make green apple juice, too. Silly, fun things like that.
Combing songs with drawing is also known to be a good technique in teaching how to draw. I follow a Japanese program for that but I’m sure you can find something like that on youtube.
Hmm, I know there’s more but that’s all I can think of for now.
