This is a wonderful way to teach geography, and all you need are boxes and paint! You could keep these in the classroom and have the students throughout the year place interesting facts they discover about each location inside the boxes.
Metric conversions. Tough stuff, but the colors make it easier to handle.
Have a square of tape on the ground, do a version of the hokey pokey. Have the students jump in and out of the square, walk to the right around the square, etc. This would be a good large motor activity to get preschoolers moving about.
