This post is showing one of the activities used to teach color recognition.
First, I chose a picture that could be divided into colored parts. I believe this was just a piece of clip art from the computer. You can also use simple color books for pictures. They do need to be at least 6-8″ large to allow for the student to be able to manipulate.
I colored each section separately.
Then, I colored corresponding colors on the tips of cloths pins.
