Find the right learning method
It is very important for parents to find the right learning methods, that is, you should be able to guide their children's learning, instead of rudely influencing them with adults' attitude of taking it for granted. Why don't you understand such a simple thing? Children have children's understanding, thoughts and inner world, which are far less mature and flexible than adults. Therefore, sometimes, we think that the simplest truth that 1 plus 1 equals 2 should also be understood by children.
The depth of knowledge starts from the simplest, and the foundation is laid bit by bit. So parents should not underestimate the simplest things and complex things, they are all made up of the simplest things. This is a key to open the maze of mathematics.
Count: Perceive physical quantity.
The first and most important step, from counting, parents let their children have a preliminary perception of the number of objects, and correspond the abstract "number" with the specific "number", knowing that "1" can represent both an apple and a ruler, and learn to write numbers from 0 to 9 correctly.
All kinds of materials can be effectively used.
In psychology, constructivism holds that children acquire knowledge of the outside world through interaction with environment and materials.
Children aged 3~6 years old still think mainly in images and do not have the ability of independent abstract thinking. They must learn through various senses and with the help of concrete and operable things.
Therefore, the operation of various materials, as a tangible thing, has become the medium and carrier for children to learn mathematics knowledge.
Only rich and diverse materials can provide children with sufficient choices to meet the development needs of different children.
In the process of fiddling with and exploring rich and operable materials, children can gradually discover and perceive mathematics, truly understand mathematics and form preliminary mathematical concepts.
Learn the large number subtraction algorithm within 100.
For example, 59-9=, 35-8=, 60-4= and so on, as long as the following minuend is less than 10.
This formula is not difficult for children. If you can't figure it out, you can get the answer by counting your fingers.
But the amount of knowledge that children need to reserve is: first, they can master positive numbers or numbers within 100 from any position, and second, they can understand the basic algorithm of subtraction. Add backward, subtract forward. It is strange that children can count their fingers when adding and subtracting within ten, but if they count more, they are often at a loss. Parents should teach them.
If the child studies hard, it won't be long before he can give an answer without counting his fingers.
