Learning the contents of the second volume of mathematics in grade one is mainly to teach students mathematical thinking methods. The standard points out that the contents of students' mathematics learning should be realistic, meaningful and challenging, and these contents should be conducive to students' active observation, experiment, guess, verification, reasoning and communication. This course is taught by independent thinking, cooperative inquiry and group communication. Specific performance in:
First, the teaching of game form is very suitable for the cognitive law and age characteristics of lower grades.
At the beginning of the new class, I designed a game and divided it into two groups to stimulate students' interest in learning and sense of competition. The two groups send representatives to the stage to draw lots according to the rules of the game, and then guide the students to summarize the methods of comparing sizes; In this way, students can not only learn new knowledge in the game, but also feel the way of comparing numbers in the game.
Second, create situations, so that students can appreciate the fun and practicality of mathematics.
In the new teaching class, I start with stories that students like. After all, the first grade of primary school is young and likes to listen to stories. I changed the example design into a conversation between two cats in a competition, which led to the problem to be solved, aroused the interest in learning and embodied the interest in mathematics. Let students feel the application of mathematical problems and knowledge from familiar real life, and feel that life can not be separated from mathematics, and mathematics is around us; So as to feel the fun and function of learning mathematics. It is the starting point and destination of mathematics learning to integrate mathematics experience into life and use mathematics knowledge to solve life problems.
Third, pay attention to the infiltration of thinking methods while learning knowledge.
Comparing the size begins with comparing the fishing of two cats, turning the practical problem into a mathematical problem-comparing the size of two numbers; Make the extracted concepts intuitive, vivid and simple. The infiltration of transformation thought is reflected in the teaching process and doing of the new curriculum, which makes students influenced by mathematics imperceptibly.
Fourth, focus on cultivating students' expressive ability and improving their language expression level.
The language expression ability of first-year students is immature and incomplete. In the teaching process, I consciously guide students to complete words and pay attention to cultivating students' expressive ability, thus improving students' linguistic expressive ability.
