How to use the materials in life to inspire children
1, say the identification number first. There is no age, place or time limit for knowing numbers. Teaching materials can be seen everywhere in life: buttons in elevators, number plates in parking lots, price tags in shopping malls, numbers on toys, page numbers of picture books and so on.
In addition to the original characters in life, you can also paste some characters in the picture book for children to find.
2. What is a sense of number?
It is the feeling of mathematics and numbers, and it is also a comprehensive ability. I consulted several senior first-line math teachers, and they gave me many examples to explain what a sense of number is. For example, with five sticks in my left hand and 10 sticks in my right hand, I can feel that there are more sticks in my right hand than in my left hand, which is the sense of number; For another example, there is a box and a bunch of candy in front of you. How many sweets can this box hold? The simple estimation result is also a sense of number; For another example, what do we think of when we mention 0.25? When you think that 0.25 is also 1/4, or 25%, what do you think of when you mention 7/8? Think of 7/8 as 0.875 and 87.5%, which are all numbers. In the final analysis, number sense is a comprehensive ability, an application of mathematics, and the ability to see the world with mathematical thinking. So how to enlighten children in real life? I started by counting. Counting from 1 to 10 is a compulsory course for many children's mathematics enlightenment, but I don't recommend counting only. It's best to count objects from the beginning: when playing with toys, count how many Legos, cars and puzzles there are. When you climb the stairs, step by step. When you take the elevator, count the floors together with the numbers jumping on the screen. Practicing counting with physical objects can clarify the corresponding relationship between numbers and things, which is not only convenient to remember the order of numbers, but also helpful to cultivate the sense of numbers. Counting from 1 to 10 is not difficult for many children. From 1 1 to 20, I didn't continue to teach reading, but led him to find the rules. Slowly, he found the rule by himself, and he can go down from 1 1, which is also the training of number sense.
3. Introduction of space and direction. Looking up, you can see the birds in the tree, the insects under the tree, the sounds in the distance, and the nearest place to your mother. As for the children in the southeast, northwest and so on, you can feel it slowly.
4, plane and three-dimensional. The plane can be put together with puzzles, and the three-dimensional can be made into a square with the help of plasticine and flattened.
5. Perception of time and clock.
6. Training in logic. Mainly through board games; When a child encounters difficulties, I will guide him to think about solutions in a certain order, which will make the logic clearer and the problem easier to solve; In addition, children over 2 years old can also introduce maze books.
7. Legal insights, to be exact, belong to the category of number sense. When recognizing the number 100 board, the law is easier to find: odd numbers and even numbers are also laws.
