Does the child need a wrench finger when he just learns arithmetic?

Many parents are often troubled by a question, that is, will their children' break their fingers' when learning arithmetic?

Some people think' snapping your fingers' is an operation.

X materialization can certainly help children understand the operation process; Another point of view is that' snapping fingers' affects the speed of operation. If the habit of' snapping fingers' is formed, it will affect the learning efficiency after school and should be stopped.

Both statements seem to make sense. Which one is right?

Let's straighten things out step by step.

First, why did the child break his finger?

When children first began to learn arithmetic, their abstract thinking ability had not been fully developed, and they could only understand the operation process through physical demonstrations, and fingers were the most convenient physical substitutes, so' snapping fingers' became the norm.

Second, what are the advantages and disadvantages of' snapping your fingers'?

Finger flick connects the abstract number with the concrete index, which can not only get the operation result, but most importantly, through the process of finger flick, let children experience the addition and subtraction process of addition and subtraction, and intuitively feel the addition and subtraction. It should be said that' snapping your fingers' can promote children's understanding of the operation.

But what is certain is that' snapping your fingers' will definitely affect the operation speed when calculating small numbers; When calculating large numbers, it hinders the display of calculation skills.

To sum up, the advantage of' snapping fingers' lies in understanding the basic concepts of arithmetic and the process of drawing conclusions, not in drawing concrete results. The advantage of' mental arithmetic' is that it can speed up the operation, but it' solidifies' the result and is not conducive to divergent thinking.

Third, what should parents do?

Children can be encouraged to "snap their fingers" when they are beginners in calculation, and parents can also show their children the correct method of numerical calculation by "snap their fingers" to help them understand abstract numbers with concrete things, so as to establish a complete mathematical concept and cultivate a correct way of thinking.

With the growth of age, gradually cultivate children's abstract thinking ability. Through the preparation process of "snapping fingers", children's understanding of calculation is also deepening, and the amount of digital operation has accumulated to a certain extent. At this time, children should be encouraged to get rid of the crutch of' snapping their fingers', from small to large, and gradually get results through mental arithmetic. For example, when my grandson is three and a half years old, numbers within 10 will generally get the results directly, and larger numbers will' snap their fingers'. At this time, parents should respect the calculation method chosen by their children, wait patiently for their children to come to a conclusion and encourage their children to succeed. Help children gradually complete the transition from' physical calculation' to' psychological calculation'.

If children need to' snap their fingers' every time after they are five years old, parents also need to pay special attention. After school, counting by' snapping your fingers' will really affect the calculation speed, reduce the learning efficiency, and even dampen children's learning confidence. At this time, we must find ways to help children get rid of the calculation method of' snapping their fingers' as soon as possible, so that children can adapt to quick mental arithmetic after school.

Encourage children to do mental arithmetic, and parents had better not force their children not to use their fingers by' stopping'. Instead, let the children gradually "automatically give up" and "break their fingers" by means of "game practice", card quick calculation and memorizing addition tables. Although the purpose of these two ways is to strengthen mental arithmetic, the influence of different ways on children's learning self-confidence is different. When children are forced to stop using "one tool" and there is no "alternative tool", they will feel "helpless" and feel difficult in calculation, which is a failed experience. When a child's ability sublimates and automatically gives up' snapping his fingers', he will feel the progress of his skills and abilities, which is a successful experience. The influence on children's self-confidence in learning mathematics in the future is completely different.

What needs to be clear is that each child's ability to understand problems and calculation speed will be different due to different genes, different growth environments and different depths of early mathematics education. No matter how long the child's' snapping fingers' lasts and how fast the calculation speed is, as long as the child keeps improving, parents should calm down and wait patiently for the child's growth. Even if the child has not made progress for a long time, we should find the reasons from the parents' education methods, and don't blame the child, especially not saying "stupid" and "others can"

Effective methods of parents, patient companionship and long-term persistence are always the best steps for children to grow up.
