In Wang Yongchun's book "Mathematics and Mathematical Thinking Methods in Primary Schools", I read that the second-grade students are lively and active, with poor persistence of attention, and the concrete components in their thinking are dominant. At the same time, the development of generalization level is in the stage of intuitive image level, which summarizes the external characteristics or attributes of intuitive concrete images of things.

The second grade is almost emotional, so the choice and application of learning methods for junior children should pay attention to visualization and game activities, and strengthen students' ability of combining numbers with shapes and intuitive geometry. Among the teaching methods, cooperative learning, game learning, competition learning and story description are often effective ways to organize and attract second-year students to learn actively and subjectively.

After reading this book, I have a more comprehensive understanding of the teaching content and teaching objectives of senior two mathematics, and have an overall impression of the cognitive level of senior two students. In order to combine theory with concrete practice, on the one hand, I need to continue to enrich my teaching knowledge, effectively design the teaching process, and truly create an effective and efficient classroom.
