First, the teaching objectives

1, initially know the meaning of "as much", "more" and "less", and compare the number of objects one to one. Can be expressed more or less clearly.

2. In learning activities, through counting and drawing, we can know who is more and who is less in one-to-one correspondence, and we can clearly express numbers in mathematical language.

3. Cultivate students' observation ability and hands-on operation ability in learning activities; Cultivate students' spirit of mutual cooperation and consciousness of using mathematics.

Second, the target analysis:

This lesson is mainly about "how much to compare". The textbook has designed interesting thematic maps. By observing the number of different types of objects, children can feel the meaning of "the same quantity, more quantity and less". Prepare for learning the knowledge of number recognition, calculation and quantity. Students have been exposed to comparative knowledge in kindergarten and have certain comparative thinking.

But children's expressive ability is not enough, so students should be trained to express their meaning clearly. In particular, the simultaneous comparison of multiple quantities is a difficult problem for children to understand. In classroom teaching, teachers should first help students understand the things being compared, then compare them one by one, and finally draw a conclusion.

Teaching emphasis: let students experience the process of "one-to-one correspondence" and find the comparison results. Teaching difficulties: focus on cultivating students' ability to examine questions and express mathematics language. Teaching preparation: courseware, graphic cards, digital cards, etc.

Design description:

For first-year students, it is not difficult to compare numbers, but it is not necessary to compare the numbers of two groups of things one by one. Through the study of this lesson, students can learn to compare things in a one-on-one way.

Introduce stories to stimulate interest in learning. At the beginning of the new class, I fully created conditions for students, used the resources provided by the teaching materials, and created vivid story situations in the form of stories that students loved, which improved students' interest in learning and activated their thinking.

Let the students try the comparison method and learn how to compare in a one-on-one way. I asked directly, "How did you tell?" Let students realize "more", "less" and "as much" through observation. Let students observe and operate freely, try various comparison methods, call the existing "how much to compare" experience in the activity, and use pictures and teachers' guidance.

Understand the truth of "how much to compare", learn to compare how much with the method of "one-to-one correspondence", and pay attention to cultivating students' observation ability and thinking flexibility. After the knowledge points are taught, let the students find out what is the same in the picture, who is more and who is less, and let the students operate independently to deepen their understanding of the "one-to-one correspondence" comparison method.
