Sense of numbers refers to people's ability to use numbers and think about problems in mathematical ways. Number sense is the ability to directly perceive logarithm. Building a sense of numbers helps children understand the significance of numbers in real life.
Mathematical thinking is a basic mathematical accomplishment, which expresses the quantitative relationship in a specific situation. To sum up in a simple sentence, number sense is the ability to perceive numbers.
For example, if you see a pile of candy, you can feel the approximate quantity; Seeing the tunnel entrance in front, I can feel that the truck I want to pass may not pass; There are also various feelings about speed, length and size, all of which are manifestations of number sense.
So how to cultivate students' sense of numbers?
In our life, mathematics is everywhere. Many times, we think it is too difficult and ignore it.
(1) Cultivate a sense of numbers, and let children see mathematics first.
To cultivate children's sense of numbers, the first thing is to make numbers meaningful. For example, if a child wants to learn what "1" is, the best way is to give him an apple or an orange and tell him that the number of this toy in his hand is "1". Add an apple to the apple, and the number here is "2". Some mathematical concepts can be accumulated through daily life experience. For example, big and small, more and less, far and near, high and short, front and back.
"Our family lives on the 4th floor. Is the fifth floor a little higher than the fourth floor? There are so many bananas in the fruit shop. Do we want more or less? We are going to the shop downstairs to buy things. Shall we go to the nearest store or the supermarket far away? "
These dialogues make mathematics an indispensable part of children's daily life. Because at this stage, children think about the world by feeling, not by logic.
(2) Cultivate children's sense of numbers and let them experience mathematics.
The establishment of number sense needs a process from concrete to abstract, and mathematics learning cannot be separated from building a real image in children's minds. Instead of letting children express it with abstract formulas? +? = 10 ",it is better to play games with him. Give him any number of building blocks. If the number given to him is 5, let him add a few more from other building blocks, add one, and count one later until it forms 10.
Through continuous physical operation and image rehearsal, we can understand the changing law of quantity and deduce other methods. Slowly, children will know that 10 is divided into 8 and 2, or 6 and 4, or even 5+3+2. It will be easier for children to accept and understand these mathematical knowledge by presenting it in a figurative and gamification way.
(3) Which mathematics enlightenment APP is better for cultivating children's sense of numbers?
Many parents are very aware of the importance of cultivating children's sense of number, and they also realize that to help children build their sense of number effectively, the occasional building block game is inevitably too thin, but most parents do not have professional guidance methods and knowledge systems, and they cannot cultivate their children's sense of number by themselves.
When choosing the enlightenment tool of mathematical thinking, the number sense planet is a good choice. Dr. Jin, the founder of Numerical Planet, is a math enthusiast and has published many popular math books. Dr. Jin spent a lot of time exploring mathematics with his two daughters, and when he chose the tools of mathematics enlightenment, he came up with the idea of making the training products of number sense enlightenment, so the number sense planet was born.
