Understanding numbers and numbers is the key and difficult point of this lesson. For children in grade one, this knowledge point is easily confused. In order to break through this difficulty, I start from the following aspects in actual teaching:

1. Create a situation to stimulate students' interest.

The theme map of the textbook is expressed in the form of scenes, but there is no such teaching situation map at hand, so I readjusted the theme map of the textbook and turned it into a teaching situation in which small animals eat (learning tools such as small monkeys are made in proportion).

When I put the pictures of monkeys, peaches, apples and so on on the blackboard at random, the children immediately opened their eyes and showed curiosity, and their interest in learning was mobilized from the beginning.

2. Let students actively participate in learning.

In the specific teaching situation, students can easily solve the mathematical problems hidden in the theme situation, and learn numbers and numbers in dynamic participation, which is in line with students' life experience and easy for students to accept, which can stimulate students' enthusiasm for learning and activate the classroom atmosphere.

3. Pay attention to cultivating students' thinking ability.

Mathematics class should pay more attention to students' mathematical thinking. In this class, I designed some objective questions at different levels, so that students can observe and think, naturally train their thinking and master what they have learned.

Reflections on mathematics teaching in primary schools;

"Ji" and "Ji" are simple expressions of cardinal words and ordinal numbers. Understanding "Ji" and "Ji" is the key and difficult point in teaching, but for first-grade children, this knowledge point is easily confused. Several indicates how many things there are. The first one is the sequence number of things. For the students who just entered the school, they are too young and have a poor sense of orientation, so it is still difficult to distinguish between numbers and numbers.

Before this part, spend a few minutes every day playing games with students about directions, so that students can know the front, back, left and right directions. Especially the left and right, I will let the students introduce themselves how to remember the left and right directions. After getting ready, I will start teaching the first grade.
