We selected some typical interview questions for elementary mathematics for children. The following questions are answered by teacher Jin Ying.
1 and 10 students line up to do the questions. There are six people on the right, and how many on his left?
Analysis: This is a queuing problem. When parents help their children to do this kind of problems, they can put them through some toys. Let the children have the concept of "platoon" first, and then guide them to ask how many people are there in Mingming's side and over there? You can also continue to ask in-depth questions: Why is a * * * 10 person, but only 9 people? Who is the missing person? By the way, see how the child's expressive ability is.
There is a mirror opposite the clock. The clock in the mirror is shown below. What's the correct time on the clock? What time is it on the clock?
Analysis: There are many knowledge points in this question. First, children should know the time, and then understand mirror symmetry, which has logical reasoning. If you encounter this problem, parents can first look at their children's mastery of time and clocks. On the issue of mirror symmetry, you can play mirror symmetry parent-child games with your children. For example, parents should first be children's mirrors. When children do something, parents will do the same. Then the child will become the mirror of the parents. In the process of playing, let the children realize that "when two people stand face to face, one's left hand is the other's right hand." When looking at pictures, children will gradually have an intuitive feeling. However, parents are not advised to give their children this type of questions when they are not familiar with a single knowledge point.
3. Huahua's house has three floors above and two floors below. How many floors does this building have?
Analysis: This is also a variant of the queuing problem. When tutoring children to do such problems, if children can't figure it out, they can first give them an intuitive feeling in the form of building blocks, and then slowly abstract it into imagination. This is also the inevitable process of children's thinking development.
There is a row of male students standing on the playground. There are six in a row. There are two female students standing between every two male students. How many female students are there in a row?
Analysis: This question examines the problem of jumping the queue. When parents are tutoring their children, if the answer is wrong. You can simplify the problem and guide the children step by step.
1 What is the gap between 6 male students and 6 male students?
2. If there are two people in each gap, how many girl students will there be?
Through the guidance of two questions, children will think in disguise when they encounter problems, and turn difficult problems into simple questions to answer.
You can also use this interesting finger game to solve it. Tutorial question: What should my mother do when she holds out two fingers, with one finger sewn in the middle, three fingers in the middle and two fingers in the middle? How many fingers are there? Then mom takes the exam again. If mom held out 10 fingers, a * * *, how many fingers would there be? (The child will quickly answer 9, which is actually 8. Can you show the child that mom's hands are growing together? Children study in a relaxed and pleasant atmosphere. )
