Teaching objectives:

Knowledge and skill goal: deepen the understanding of the shape characteristics of cuboid cubes, distinguish the concepts of surface area and volume, master the calculation of surface area and volume skillfully, and solve some practical problems.

Process and Method Objective: By guiding students to discuss, explore, cooperate and communicate, establish a preliminary concept of space and develop thinking in images. Cultivate students' self-summary ability of knowledge.

Emotional attitude and values goal: By solving practical problems, students can feel the close relationship between mathematics and life, and form the experience of actively participating in mathematics teaching activities and actively cooperating with others to achieve success, and establish confidence and courage to learn mathematics well.

Teaching emphasis: help students organize the knowledge of cuboids and cubes and make them systematic. Understand the meaning of volume and surface area, and use formulas to solve practical problems.

Teaching difficulty: to cultivate students' ability to solve practical problems by comprehensively applying what they have learned.

Teaching process:

First, create a situation to induce vitality. (2 minutes)

The teacher brought you some pictures today. Please enjoy it together. What do you think of in the process of appreciation?

Indeed, they can remind us of the recent research on cuboids and cubes. Today we will review the knowledge of cuboids and cubes.

Write on the blackboard: Review the arrangement of cuboids and cubes.

Identify the target: introduce the conversation, arouse students' association from the objects in life, and introduce the review of this unit knowledge. Determine the teaching objectives of this course

Second, independent inquiry, cultivate vitality (9 minutes)

Question: Do you have any questions about this part of knowledge?

Review and arrangement

1, question prompt 1: Please open your books and see what we have learned about cuboids and cubes in this unit. (blackboard writing: sum of characteristics, surface area, volume and side length, common units and conversion,)

2. Next, review the knowledge about cuboids and cubes from three aspects: characteristics, surface area, volume and side length, common units and conversion.

3. Find the classroom paper "Characteristics of Cuboid and Cube" and tell me what you have learned.

4. Report by name.
