When she's finished drawing, DON'T LOOK at the image. Instead, get your own sheet of blank paper and sit with your back facing her. Her job is to describe to you her drawing in enough detail and geometric and positional language that you can draw your own version of her original image.
For instance, she might start out by saying, "Draw a circle". Well, without having seen the original, you may pick up the pink marker and draw a huge circle that takes up the entire page. What she'll soon see is that she needs to say something like, "Draw a small gray circle with a black circumference." Then she has to convey to you that there is a purplish-blue triangle hanging from the bottom left side of the circle. But, she'll have to let you know that it is an equilateral triangle, as opposed to a bottom-pointing isosceles triangle or something else. She also have to let you know that the triangle is similarly sized to the circle. Next, she'll have to use her language to get you to draw the kite/diamond and the floating orange pentagon.
You can make up your own rules, such as the listening artist is allowed 5 clarifying questions, or the original artist is allowed to peak at the listening artist's work as it's being drawn so she can be more exact with her descriptions.
The possibilities are absolutely endless, and there's no reason multiple kids couldn't participate in this, if you're needing a little break. One child could still be the original artist and a whole group of kids could be the listening artists. Have fun! And, as always, happy learning!
