1, demonstrate with objects or models.

You can prepare some sticks or colored cards to let students understand the meaning of division intuitively. First, divide eight sticks or cards into five parts, and put two sticks or cards in each part. Then ask the students: How many sticks or cards are there in each part? Students will answer: each copy has 2 sticks or cards. Then ask: what is the result of dividing 8 by 5? Students will answer: 8 divided by 5 equals 2. In this way, students can operate by themselves, intuitively understand the meaning of division and have a deep memory.

2, with graphics or charts to demonstrate.

You can draw a simple graph or chart to help students understand the meaning of division. For example, draw a square, divide it into five equal parts and mark it with numbers or symbols. Then ask the students: How many parts is this square divided into? Students will answer: this square is divided into five parts. Then ask: what is the result of dividing 8 by 5? Students will answer: 8 divided by 5 equals 2. In this way, students can intuitively understand the meaning of division through graphics or charts, and remember it deeply.

3. Use the counter to demonstrate.

You can use a counter to demonstrate the calculation process of dividing 8 by 5. First, the number 8 on the counter is represented as 8 beads, and then it is divided into 5 parts, each with 2 beads. Then, ask the students: How many beads are there on the counter now? Students will answer: Now there are always 10 beads on the counter. In this way, students can intuitively understand the meaning and calculation process of division, and can use the counter to make simple calculations by themselves.

Math skills in the second grade;

1, establish mathematical thinking.

Mathematics is a subject that needs abstract thinking and logical reasoning. To learn mathematics well, we need to establish mathematical thinking first. In daily life, students can be guided to think with mathematical thinking, such as counting, comparing sizes, calculating distances and so on. Through these exercises, students can gradually develop mathematical thinking and use it to solve practical problems.

2. Do more exercises.

Mathematics is a subject that needs a lot of practice. Only through a lot of practice can we master mathematical knowledge and use it flexibly. In practice, students can gradually improve their mathematical ability and problem-solving skills through repeated thinking and trying. Therefore, students can do more exercises and practice the wrong questions again and again until they fully master them.

3. Pay attention to the study of basic knowledge.

Mathematics in the second grade is the basic stage, which requires students to pay attention to the study of basic knowledge. In the process of learning, you can gradually master the calculation ability, geometry cognition and so on. These basic knowledge are very important for future study. Therefore, students need to listen carefully, think actively, master every knowledge point, and lay a solid foundation for future study.
