The example cited in the title, you can use it to play with children. Children who have just entered kindergarten usually blurt out the answers with many apples.
When you meet many parents, you will be crazy at this time: how can this be wrong? I thought you could count. Count it. It's over. What should I do if my baby finishes math?
In fact, it is not that children have no talent, but that parents neglect to cultivate an important ability-sense of number!
1, what is number sense ability?
Simply put, it is the baby's ability to perceive quantity and the ability to correspond numbers (symbols) with quantity.
take for example
Three oranges and three strawberries, children should be able to know the difference by counting, but the numbers can be the same;
Three oranges and six oranges, children can know that the same thing can have different amounts;
Four apples and five grains of rice, if the child understands that size and shape have nothing to do with quantity, he can answer correctly;
2. What's the use of cultivating a sense of numbers?
It's so useful!
A good foundation for learning mathematics begins here.
For example, in the routine of application problems that should be mastered before going to primary school, one of the most representative topics is:
Five girls, four boys and two teachers are on the bus. How many people are there on the bus?
If children can only count simply, the answer to this question will be confused.
3. How to cultivate a sense of numbers?
Pick a few key points.
1, don't learn "number recognition" yet.
What a child can remember is basically what he understands.
As the last article said, we must take our children to count the things in life, whether it's building blocks, stairs or cooking jiaozi.
If he has never done such a calculation, and just started to recognize the numbers 1, 2, 3, 4 when he first came into contact with mathematics, then it would be fatal to mathematics learning!
For example, if you teach him 2+3=5 several times, the child may not know it, but you tell him that I will give you five chocolates, and you will eat two today and three tomorrow.
When he saw the chocolate in his hand, he immediately understood that 2+3=5, and even asked, is it okay if I eat four today and save 1 tomorrow? 4+ 1=5。
2. Cultivate children to play more classified games.
The first module of children's mathematics is "perceptual set", and one of the modules is to teach children to learn classification.
Red clothes and red trousers are the same, apples and oranges are the same, umbrellas and rain boots are the same. ...
In the classification, children will know more about the real world and know the knowledge of number, quantity, shape and size which are very useful for thinking exercise.
In the classification game, the concept of different sets of children will be cultivated.
There is no shame in counting your fingers.
I wonder if it's the vanity of my parents. Many parents think it is shameful for children to count their fingers, and they should cultivate their mental arithmetic ability.
In fact, the flexible use of finger perception will better let children understand how to use mathematics.
In some countries in Europe and America, it is generally verified that the better students know fingers in grade one, the better they compare and estimate numbers in grade two, and the appearance of fingers directly indicates their calculation results.
So don't stop when you see a child snapping his fingers. In recent years, there is a saying that the reason why China's junior children are better than foreign children of the same age in math learning is because they have experience in using chopsticks.
Welcome to pay attention to pre-school mathematics and work with experts to cultivate children's thinking nuclear weapons.
