The child who did the math 32-1=31 was crossed out incorrectly, the teacher gave an answer that made many people angry

In recent years, many parents with elementary school age children find it very difficult to teach their children to do math. Because instead of being easy to understand and simple, many basic problems today require logical conclusions that are very difficult to give the most complete and accurate results.

For example, the story of a mother below. According to Share, this mother of one child attends an elementary school in China. Her daughter has just taken her 3rd grade math exam and the results of her math problems have made students and parents very upset. When the mother posted it online, many people were also upset. Specifically, the problem question:Tieu Minh’s age is 8. The age of the mother next year will be four times the age of her child. How old is Tieu Minh’s mother?”

An elementary school student solves the following math problem:

Next year’s mother’s age will be 4 times her child’s age => next year’s mother’s age will be: 8 x 4 = 32 years

So the mother’s current age is: 32 – 1 = 31 years.

However, the 31-year-old student’s answer was crossed out by the teacher incorrectly.

Then, the teacher explains that the problem needs to have 2 solutions with 2 different answers to solve it.

Where, “The age of the mother next year will be 4 times the age of her child” and I don’t know what year I am. So I have to give 2 cases, this year or next year.

+ Case 1: Next year’s mother’s age will be 4 times her son’s age this year

=> Mother’s age next year is: 8 x 4 = 32 years. And the mother’s current age is 31 years.

+ Case 2: Next year’s mother’s age will be 4 times her son’s age next year

=> Mother’s age next year will be: (8 + 1) x 4 = 36. And now mother’s age is 35.

After the math problems were posted on social networks, many people were outraged by the teacher’s confusing explanations and thought that these questions were not suitable for 3rd graders.

When the problem was shared with a group of parents of elementary school students in Vietnam, many people were angry, angry, and even explained to give a different answer. “Because next year the age of the mother is 4 times the age of the child, not next year the age of the mother is 4 times the age of the child this year. And next year, the mother’s age will be 4 times her age. I don’t see anything wrong with the title. It’s just a bit difficult for elementary school students. Answer 35 is standard, only those who like to argue are 31″;

“Read a math problem whose completion is 31, it’s okay. This lesson includes an assessment of students’ abilities”; “35 is the standard because now when Tieu Minh is 8 years old, next year he will be 9 years old, but then his mother was 4 times his mother, now he is 35”; “Determine next year urgent, next year you will be 9 years old. That’s right”; “Read the topic but get confused, no wonder now students play but can’t learn”; “If the answer is 31, then add the word “4 times Minh’s age now”. If not, it means that if mother is 1 year older, then Minh is also 1 year. If mom is 36, then Min is 9 years old…

In fact, situations like this happen quite a lot and the cause is that children have not formed the skills and habits of reading questions carefully when taking tests. Mathematics is difficult in that, not only careful calculations, this subject also requires the ability to read and understand and find the exact terms of the problem.

In a math problem, if you do it in a hurry without paying close attention to the problem, it will cause errors in the answer. Many parents wonder that their children’s math skills are good, but for some reason, they always do math problems wrong. An applied problem like the one above will contain many types of information and suggestions for students to solve the problem. After students master the information from the problem, the formula is applied and calculated carefully, the answer given will be correct. Therefore, the prerequisite before starting to take the test is to read the questions carefully.

If children form the habit of reading the requirements carefully, they will easily get high marks in exams, and also help them become more confident in their studies. Elementary school is an important time for students to form good habits and behaviors – which directly affect later life. So how to help children get used to observing elementary math problems and the problems they face in life?

1. Reading questions is the first step in cultivating the habit of taking questions seriously

Training students in the habit of reviewing questions is a long-term task, requiring the cooperation of parents and teachers. In the teaching and learning process, parents can use their fingers to read the questions with the child, speak slowly so that the child understands the problem, if the child does not understand, then read it again 2-3 times.

Advantages: attracts attention, while strengthening children’s text reading skills. Elementary school students have excellent ability to recognize and remember. If parents often study and read with their children, it can also help children expand their knowledge.

2. Practice reading comprehension habits

The advantage is that it can further increase children’s understanding and impression of various topics. Since action and thought are closely related, reading a topic well is like reading a story. So, if the length of the rope is multiplied by 10 cm, how many cm is the length of each rope? At this time, you should let the child do it himself, figure out the length of each half-fold by himself, when the child understands clearly, the parent should praise and encourage the child.

3. Highlight the main points and minor points while reading

Math application questions are often content rich and informative. Therefore, you are required to draw the main points while doing the test. At the same time, filtering important information, it helps them accurately understand the requirements of the question as well as its solution.

Cultivating this habit is not “a day or two”, but needs to be cultivated over a long period of time. Therefore, accompany and encourage your children more so that they acquire good habits, which are useful for increasing their ability to receive information and their overall quality.
