Teaching content: textbook page 59, example 7, give it a try. Thinking and action on page 60. Teaching objective: 1. Make students go through the process of finding the difference between two numbers in practical problems, understand how much one number is more (or less) than the other, and learn to solve similar simple practical problems in daily life.
In the process of solving practical problems, students can initially understand the characteristics of mathematical thinking, feel the value of mathematical abstraction, cultivate their interest in learning mathematics and enhance their awareness of applied mathematics. Carry out environmental protection ideological and moral education in time.
Teaching emphasis: guide students to explore how to calculate such problems continuously. Teaching difficulties: guide students to understand the quantitative relationship of such problems and the thinking methods to solve them. Teaching preparation: courseware, blue flowers and red flowers teaching AIDS, and every student has graphic learning tools.
Analysis of learning situation: It is the first time that students have formally learned to solve such problems by using subtraction to solve the problem that one number is greater than another. I have seen more than a few pictures before. Therefore, in teaching, we should make full use of the concept that students know as much as Unit 2 of Book 1, and who has more and who has less, and feel the process and method of finding a number more and a number less in the process of setting up learning tools.
Draw a contrast. Teacher: Students, today our parents come to our class to listen to our math class. Are you confident to show them your best performance in class? So today, let's compare who listens most attentively, speaks most actively and has the most complete language. Teachers in comparative life: There are many things to compare in life. Can you give me an example? Students speak freely. Conclusion: There seems to be a lot to compare in life.
Learning skills of first-year mathematics
1. Looking for mathematics from life, mathematics is a science closely related to life. It is not only some abstract symbols and formulas, but also a summary and expression of the laws of the objective world. Therefore, it is an important way to cultivate children's interest and curiosity in mathematics by letting them discover mathematics from their lives and feel its interest and practicality.
2. Practice math from the game. Games are children's favorite activity and their most natural way of learning. Through games, children can exercise their attention, memory, imagination, creativity and logical thinking ability in a relaxed and pleasant atmosphere. Therefore, using games to practice mathematics is an effective way to improve children's basic mathematical ability and self-confidence.
