I. Counting and radix
This part of education mainly involves singing, counting, quantity, numbers, mathematical language and so on. Most parents in China only pay attention to the singing part. The most obvious performance is that many children can count from 1 to 100, but they don't know how to get twelve strawberries or give him a bunch of strawberries, and they don't know how to count how many strawberries there are.
In fact, thinking is the most important thing in mathematics education. Singing numbers only makes children remember easily, but it can't help children form mathematical thinking patterns. So parents need to teach their children something other than singing numbers.
For example, in the counting part, parents should teach their children to count in groups, such as counting in units of ten; Writing needs to help children write numbers within 20; In mathematics language, children should be able to compare numbers within 10 and know the meanings of words such as greater than, less than and greater than. We didn't know the simple quantitative relationship until it was greater than 1 less than 1, such as 1 chopsticks, a strawberry and so on.
Second, the operation
Before going to school, parents are advised to let their children master the operation within 10, but they should not know the answer by rote, but really understand the meaning of addition and subtraction. For example, addition means merger and increase, and subtraction means separation and taking away. It is best to let children understand the meaning of addition and subtraction with lively and interesting scenes. For example, if children like to eat cookies, show them how to take them away, how to do subtraction, how to do addition, and introduce mathematical language in time to let them know that mathematics conforms to "+"and "-".
Three. Measurement and data
For preschool children, parents should help their children to form a simple way of thinking of measuring, recording and comparing when they carry out mathematics enlightenment education. Commonly used measurement methods include the length, height, weight, volume, size and so on of coins. The measurement method is to measure the length of two tables with a wooden stick in a way that children can understand, and then compare them; Or sort the mixed fruits first, and then compare their weights with a balance.
More importantly, after measurement and comparison, children must be able to express themselves in their own language and describe their own conclusions after measurement and comparison.
Fourth, geometry knowledge.
When teaching geometry knowledge to preschool children, we should not only let them understand graphics, but also help them form spatial thinking. You can use common educational methods, such as puzzles and building blocks games, to let them know up, down, left, right, front, back, side and side.
Parents should pay attention to that in addition to two-dimensional graphics, it is best to let children have a certain understanding of three-dimensional graphics, such as how many sides does a cube have? How many sides does a square have? Two triangles can form a square, and so on.
The above is the content of mathematical knowledge that should be taught to preschool children for the enlightenment of mathematical thinking, but when parents educate their children to learn mathematical knowledge, it is most important to pay attention to cultivating their children's mathematical thinking, and pay attention to cultivating their logical thinking and abstract thinking.
