1. Make a measuring scale on a wall till 180 cm. Measure the height of every student in your class on that scale
2. If you walk fast you will reach finish line sooner or later? How to check? Keep a walking race. 5 Students walk from one end of classroom to other end of the room. See who reaches first. How is speed of the student related to time here? Discuss and share.
