1, easy before difficult

Arithmetic is complicated, and it is difficult for children to accept it if they teach difficult arithmetic from the beginning.

Parents can integrate their lives into their children's math learning, such as going to the supermarket to buy apples, and let the children choose and count themselves. After returning home, parents can ask their children to wash two apples and ask them how many apples each has left after eating.

In this way, letting children unconsciously contact and learn mathematics in life can improve their interest in mathematics and help them understand the importance of mathematics in life.

2. Use decomposition skills to teach children from the beginning of decomposition and combination. At the same time of division, use language to express. Be sure to say it with your mouth. The child who can speak out means that she really has it. Start with less than 5. Let's talk about decomposition 2 first. Remember to put them together after each separation.

3. Remember large numbers in your mind, add and subtract decimals: Addition: Remember large numbers in your mind and count decimals up, for example, 4+2= remember 4 in your mind, count up two numbers, 5 and 6, and you will get the result. Subtraction: Remember large numbers and reciprocal decimals in your mind, for example, 6-3= remember 6, the reciprocal three numbers, 5, 4, 3.

Parents need to cooperate with their baby to add and subtract within 30 kinds of 10 every day to improve their baby's arithmetic ability, and be careful not to let them count their fingers, so as to cultivate their baby's habits and mental arithmetic ability.

Introduction to addition:

Addition (usually indicated by the plus sign "+") is one of the four basic arithmetic operations, and the others are subtraction, multiplication and division. For example, in the picture below, * * * has a combination of three apples and two apples, and * * * counts as five apples. This observation is equivalent to the mathematical expression "3+2 = 5", that is, "3 plus 2 equals 5".

In addition to calculating fruits, you can also calculate other physical objects. Using system generalization, addition can also be defined on more abstract quantities, such as integers, rational numbers, real numbers and complex numbers, and other abstract objects, such as vectors and matrices.

In arithmetic, the addition rules involving fractions and negative numbers are designed.

Addition has several important properties. It is interchangeable, which means that the order is not important, it is interrelated, which means that when more than two numbers are added, the order in which the addition is performed is not important. Repeatedly adding 1 is the same as counting; Adding 0 will not change the result. Addition also follows related operations such as subtraction and multiplication.

Addition is one of the simplest digital tasks. The most basic addition: 1+ 1 five-month-old babies and even other animal species can be counted. In primary education, students are taught to calculate the superposition of decimal numbers, starting with one digit, and gradually solving the more difficult number calculation.
