Line the floor with gym mats or perform the exercise on the grass to protect children from injury if they fall during the exercise.
Line up the three strongest, biggest students in the front, followed by the two next-strongest students in a row behind the first three. Line up the lightest student by himself in a third row behind the two.
Have the first three students get down on their hands and knees with their backs straight. Have the next two students climb on top of the first three, placing their hands on the shoulders of the bottom row of students and their knees on the students’ backs.
Help the sixth student climb up the two rows of students to the middle of the top two. Have him place his hands on their shoulders and his knees on their backs. Take a picture of the pyramid, then have the top student climb down, followed by the second two and then have the bottom three stand up.
Challenge the students to arrange themselves back into the pyramid, allowing different students to fill different positions. Ask them to consider other ways they might also be able to build a human pyramid, such as by all the students lying on their backs on the ground in a one-dimensional pyramid shape that forms on the ground rather than up into the air.
