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, when a child sees a pile of candy, he 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.
How to cultivate students' sense of numbers? Share a few daily methods.
(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? "
(2) Cultivate children's sense of numbers and let them experience mathematics in the game.
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.
After constant physical operations and image drills, 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) It is very important to cultivate children's sense of numbers and choose tools.
Many parents are very aware of the importance of cultivating children's sense of number, and they also realize that to really help children effectively establish their sense of number, occasional building block games are inevitable, but most parents do not have professional guidance methods and knowledge systems, and because of the usual time constraints, they cannot personally cultivate their children's sense of number.
Love to play is a child's nature, and the so-called "playing middle school" and "playing" are the key points. Mathematical Planet Mathematical Science Park integrates mathematical knowledge points into the game, presents various learning principles in the game, learns and understands in a gamification way, turns the game into a process of solving mathematical problems, combines rigorous mathematical knowledge with interesting games, and adopts interesting gamification learning methods. In fact, every child is a born mathematician. Only by choosing the right way and efficient tools can children fall in love with mathematics from an early age.
