 One way to help a child learn about colors is through sorting. All you need are several small objects that are different colors, making sure there are a few of each color. You can say to the child, let's sort these by color. We'll put all the green ones together in one group, all the red ones together in another group, and all the blue ones together in another group. You can first show them how to do it with one of the colors. Then, they can try sorting the other colors. You can use any small objects for this activity. Sorting by colors will help improve a child's logical thinking.
