Parents: Hello, everyday mom. In the process of tutoring Tong Tong, I found two more difficult problems. Please help me. One: Problems arranged according to certain rules. She can't understand such a problem, and I always don't understand how to help her understand it. Two: When learning simple addition and subtraction, children often use their fingers, but some parents told me that it is not good to use fingers, just use physical objects. But I think it's quite simple to use your fingers, that is, add or subtract more than six, and she will be confused! Mom: Hello, Mom Tong Tong!

The two things you said belong to children's mathematical cognition, one is logical reasoning and the other is calculation. For children, mathematics can't be as abstract as knowledge points in other fields, and it can be assisted by official feelings such as tasting, listening and touching, so it really takes a long time to practice before children can master and use it skillfully.

Let's talk about the first one: problems arranged according to certain rules. If children want to understand the rules, they must first learn the division of the same combination. Of course, if you want your child to be interested, you have to import from the topic she likes to listen to. You can play games with children with peas, fruits, color cards or other things. For example, it can be assumed that red beans and mung beans are used by the smurf father to make magic potions, but the formula is very particular. First put only one red bean, then two mung beans, then one red bean and two mung beans ... As long as children can skillfully play these physical games in various ways, then they can return to the plane and cut them into various shapes with color cards. Finally, they can practice with symbols of colored strokes. This process can help and guide children to gradually understand and infer from concrete objects to abstract symbols.

Let's talk about simple addition and subtraction first. The reason why children use their fingers to assist in calculation is because they lack the support of concrete images in their hearts. In other words, we have not been able to respond to several things at once, nor can we directly answer them with conditional answers. So it's better to go back to specific physical exercise. Only by letting children really understand and understand the concept of more and less can they practice conditional mental arithmetic skills on the basis of repeated practice.

Only in this process, it is suggested that we must start from simple topics and practice from topics that children have already learned to enhance their self-confidence. When she is already very skilled and thinks she can do it, she will add a little difficulty appropriately, so step by step. There are also many ways to practice, which is interesting. It is best to practice with everything that children are interested in when playing outdoors. I believe it won't be long before Tong Tong can master it skillfully. Come on!
