Physical group activities are another method which teachers can effectively use. Here teachers can even use simple exercise techniques where the teachers should instruct preschoolers to do simple exercises like stretching their hands up and down or jumping. At the beginning of each activity, announce a prize for those who listen and follow the instructions carefully until the end. During the activity, instead of saying up and down in a rhythmic way, say "up, up, and down" or "up, down, and down." Remove all those who have made a mistake. This is a simple technique which teachers all over the world use in various forms. But, it is effective in helping preschoolers to keep their attention on a single event for a long time. It is also a great way to burn off some excess energy!
