First, master the skills and count easily
1. First of all, the method of filling ten is a very practical skill. When calculating the addition within 20, you can divide the smaller one of the two numbers into two numbers and add them together, and then make up 10, and then add another number with 10, which makes the calculation easier. For example, to calculate 8+9, you can divide 8 by 2+6, then add 2 and 9 to get 1 1, and then use 10+ 1 to get1.
2. Secondly, decomposition is also a common skill. For some larger numbers, you can divide them into smaller numbers and add them up, which makes it easier to calculate the result. For example, if you calculate 12+ 13, you can split 12 into 6+6, then add 6+ 13 to get 19, and finally add the two results to get 25.
3. In addition, the formula method is a convenient and quick skill. For some basic mathematical operations, you can make up a formula to remember, which can help you calculate quickly. For example, for the multiplication formula table, "one by one gets one, one by two gets two, and one by three gets three …", so that the answer can be found quickly in the calculation.
Finally, induction is an important skill. For some complex mathematical problems, we can simplify them into some simple patterns or theorems to solve them, such as using distribution law to calculate the addition and subtraction operations in brackets.
Second, open the door to mathematics
1. First of all, we need to master various mathematical skills and methods through study and practice, such as the method of adding ten, the method of decomposition and the method of formula. These skills and methods can not only help us to calculate mathematical problems quickly and accurately, but also help us to better understand and apply mathematical knowledge.
2. Secondly, we need to transform mathematical knowledge into our own way of thinking through induction and summary. By summarizing various mathematical problems and models, we can better understand and apply mathematical knowledge and improve mathematical thinking ability.
Finally, we need to consolidate our mathematics knowledge through continuous study and practice. Only by continuous study and practice can we truly master the knowledge of mathematics, open the door of mathematics and enter the magical world of mathematics.
Learn math easily.
1. First of all, we can use examples from life to understand mathematical knowledge. For example, the process of calculating change when shopping can better understand the operation rules of addition and subtraction.
Secondly, we can use games and competitions to stimulate our interest and enthusiasm in mathematics. For example, playing math games with classmates can improve the speed and accuracy of calculation and increase the fun of learning.
Finally, we can use graphics and images to help us better understand mathematics knowledge. For example, mathematical concepts and principles can be understood more intuitively by drawing graphs or images to express quantitative relations or spatial relations.
