According to the new curriculum standards of primary school mathematics and the requirements of school preparation guidance, the mathematics content that preschool children need to learn can be summarized into the following seven aspects.
Digital sum count
Teaching children to count seems simple, but it actually contains a lot of knowledge. Most children can recite numbers, but they can't correspond to each other. So parents can train their children to start by counting items and then gradually increase the number of items. Moreover, parents need to guide their children to tell the total. The goal is to enable children to consistently count objects within 20, and eliminate the interference of object size and arrangement, and tell the total number of objects.
In addition, another manifestation that children can understand the correspondence between several things is that they can take things according to numbers. Parents can give their children clear digital instructions to help them get things. For example, go to the supermarket, ask the children to help pack three apples, take two boxes of blueberries and so on.
Shape and space
Preschoolers need to learn basic geometric shapes, such as circles, squares and triangles. And feel the concept of space, such as up and down, front and back, left and right, inside and outside. To prepare for learning geometry and three-dimensional graphics after primary school.
First of all, parents can lead their children to know the graphics in life, such as round manhole covers, square bread, triangular clothes hangers and so on. Second, teach children to know the direction. The position is relative. It is suggested to take the child's body as a reference and ask the child, "Is the toy car on the baby's left or right?" ; When you go out to buy food, you can also help your child understand the location of the supermarket by using local language. For example, "The supermarket is next to the convenience store, opposite the bank, and the delicious jiaozi is upstairs." Wait a minute.
Secondly, children can be asked to help put things away, which can not only train their familiarity with other words, but also learn the expression of position by imitating parents' instructions.
Quantitative comparison
Learn to understand the relationship between size, such as comparing size, weight, length, etc. , and when comparing a single variable, you can exclude the interference of other variables. Watermelon is very big, but the price is not as good as a small watch.
In daily life, parents can let their children weigh and measure who is taller, father or mother, pencil or ballpoint pen. Ask your child questions at the right time. How many fruits are there in the basket? Is the basket heavier or the watermelon on the table? Cultivate children's sense of number and quantity through constant touch and practice. After entering primary school, they will not write an answer with the pen of 1cm.
Set and classification
Learn to classify items, such as grouping according to color, shape and other characteristics. This is an important step in mathematics enlightenment. Cultivating the thinking habit of classified thinking is helpful for students to solve difficult problems quickly after entering senior three, and to discuss the problems in different situations and get answers.
Parents can start by training their children to arrange toys, and can match and classify items according to their attributes to form different collections, such as by size, weight and length. The same group of objects can also be classified in different ways, such as building blocks, electric machinery, doll fabrics and so on.
Regularity and sequence
Feeling the law and order of the world is also an important part of preschool children's mathematics enlightenment.
In fact, sorting things can be seen everywhere in life. Mothers take their children to play together, and they can go to parks, supermarkets, shops and so on. Observe the scenery on Zhouguo, find out what things are arranged regularly, and let the children talk about how they are arranged (such as handkerchiefs, towels, flowers beside curtains in shop windows, and the arrangement of roadside fence tiles). Through these arrangements, children can have a conceptual understanding of things in life, which is very beneficial to the cultivation of children's thinking.
Simple operation
I don't want my child to break his finger in the first grade so that he can train before going to school! In fact, formulas composed of numbers and mathematical symbols are mostly cold and abstract in children's eyes. Therefore, in the early days of children's exposure to arithmetic, the best education method is to integrate abstract mathematical knowledge points into specific life scenes to help children understand the mathematical logic behind formulas. Simple addition and subtraction can be practiced with specific items, for example, when going to the canteen, let the children calculate the number of things they want to buy, or how much is left in the budget of ten yuan.
Understand time, calendar and money
Time, calendar and coins are not only important knowledge in primary school, but also necessary skills in life. If preschool children are exposed to this knowledge in advance, they can become more independent and brave as soon as possible, and establish a correct view of time and money.
Get up every day and ask your child what day it is today. Do you want to go to school today? In fact, seven days a week and 365 days a year are the rules of life, and learning to read calendars is also one of the important skills. You can also give children the knowledge of science leap year and leap February, and enrich their knowledge reserves. There are also many coin simulation toys in the market, such as "playing house" and "supermarket cashier", which can not only help children understand coins, but also bring the parent-child relationship closer, killing two birds with one stone.
