On a spring day, we went fishing. First of all, we cut colorful fishes. Next, we used colorful paper clips. Every fish had a paper clip with a different color. With a magnet and a spool of thread, we made a fish hook then fishing got started. I was mentioning a color to him and he fished base on the color of the paper clip. It was a good practice to notice small things and also useful for impulsive children.
