"Axisymmetric Phenomenon" Axisymmetric PPT Courseware 4

Description

"Axisymmetric Phenomenon" Axisymmetric PPT Courseware 4

Students’ existing foundation

Knowledge base: Students have a preliminary understanding of axisymmetric figures in primary school, but their understanding is only at the perceptual level, and they still lack understanding of specific related concepts.

Empirical basis: Many things with axial symmetry in nature and real life provide an experiential basis for students' cognition.

Problems faced by students

Students in this age group have less experience in mathematical activities and lack learning methods and language generalization abilities. Therefore, they may have problems with unclear analysis and understanding of concepts.

The descriptions related to this lesson in the "Course Standards" are:

Understand the concept of axial symmetry through specific examples, understand the concept of axial symmetry graphics, and recognize and appreciate axial symmetry graphics in nature and real life.

Break it down from a cognitive perspective:

Knowledge classification: the concept of axially symmetrical figures, the concept of two figures forming axial symmetry.

Cognitive level: understand, understand. Action verbs include: recognize, appreciate.

Subject content: Understand the characteristics of axially symmetrical phenomena from specific examples, understand the concept of axially symmetrical graphics, and recognize and appreciate axially symmetrical graphics in real life.

learning target:

1. Perceive the axial symmetry phenomenon in life by observing rich life examples.

2. Understand the concept of axially symmetrical figures through activities such as thinking and searching.

3. Through paint blowing experiments, comparative exploration and other activities, understand and appreciate axisymmetric figures in life.

Evaluation Task 1 (for Objective 1)

Students can watch videos and pictures carefully and think positively.

Evaluation task two (for goal 2)

Students can find examples of axial symmetry in life based on their own perceptions, and finally be able to use examples to describe the definition of axial symmetry figures.

Evaluation task three (for goal 3)

Students can actively participate in activities such as paint blowing experiments, comparative exploration, etc., and can experience the fun of mathematics, feel the joy of success, and understand and appreciate axisymmetric figures in life.

【plan for design】

1. The introduction of magnetic sheets for children's toys is not only beautiful but also easy to operate, which is conducive to mobilizing students' enthusiasm for creation.

2. The continuation of after-class design activities reflects the concern for students’ long-term development.

3. Cultivate students’ hands-on ability, innovative thinking ability and awareness of group cooperation.

4. Make students realize that mathematics comes from life and is applied to life.
