Case design activities: 1. Learning measurement calculation of chalk, disposable cups and bottle-shaped volume (volume) calculation; 2. Learning to explore the ship tonnage measurement and calculation. Activities Objectives: (1) To further consolidate the calculation of the volume of the cylinder, learn the calculating method of the chalk-shaped, disposable cups and the bottle-shaped and pebble-shaped irregular bodies, and solve the mathematical problems by using the converted thoughts. (2) To grasp the method of finding out the irregular body, and to explore the method of calculating the tonnage of the ship by the method of drainage. (3) develop students’ spatial imagination ability, stimulate their ability and interest to solve practical problems in life.
