It involves four basic operations: addition, subtraction, multiplication and division, and the combination of these four operations. The learning goal at this stage is not only to let students master the basic concepts and skills of these operations, but also to cultivate students' mathematical thinking ability and problem-solving ability.
course content
When learning elementary integer arithmetic, students need to master the rules and methods of four basic operations: addition, subtraction, multiplication and division. For example, addition requires adding two numbers, subtraction requires subtracting one number from another, multiplication requires multiplying two numbers, and division requires dividing one number by another. These basic operating rules and methods are widely used in daily life and study.
teaching method
Next, students need to learn how to combine these basic operations for mixed operations. For example, you can add and subtract first, then multiply or divide; You can also multiply or divide first, then add or subtract. In the process of learning mixed operation, students need to master the order and laws of operation step by step, and be able to use these laws flexibly to solve practical problems.
In the process of learning integer elementary arithmetic, teachers should pay attention to cultivating students' mathematical thinking ability and problem-solving ability. Through some practical examples and problems, let students learn and master the rules and operation methods of integer elementary arithmetic in practical operation. At the same time, teachers need to encourage students to think more and practice more, and constantly improve their mathematical literacy and problem-solving ability.
abstract
In a word, integer elementary arithmetic is an important content in the fourth grade mathematics of primary school, which involves the combined application of four basic operations: addition, subtraction, multiplication and division. By learning and mastering these basic concepts and skills, students can better understand and apply mathematical knowledge, and improve their mathematical literacy and problem-solving ability.
