Teaching content: Beijing Normal University version of mathematics sixth grade. Teaching objectives: 1. Combination of specific situations and practical activities to understand the meaning of cone volume or volume, to further understand the meaning of the object volume and volume. 2. Guide students to experience the conjecture - verification - Conclusion - application of cone volume exploration process, experience analogy, transformation and other mathematical ideas. 3. Grasp the calculation method of cone volume, can correctly calculate the volume of the cone, and solve some simple practical problems, feel the connection between mathematics and life. Teaching pieces: [piece] a bold guess willing to practice division: bold guess, how to calculate the cone size?
