As kids, we often think of first grade math as simple too, just revolving around addition and subtraction, multiplication, or counting. However, as I grow up to do homework for myself or my children, many adults find that today’s Elementary math is also skillful and exhausting.
For example, in a recent story, a mother posted her son’s problem online with the message: “Can you explain this article? I found myself stupid, I finished college but couldn’t solve the second grade problem.“.
The exercise is attached: “There are 45 sheep on the boat. 5 children fell into the water. How old is the captain?“.
The problem of the facts on the one hand, the answers on the other is controversial
After reading all of them, all parents were confused before one-sided task, but asked for a form. The above problem is known to be found on page 63 of the second grade math book.
Most parents think that the problem cannot be solved because the facts and the answers are different. There are many assumptions that have been made. One parent said this is just a riddle for students. It can be understood that there were 45 sheep on the boat, 5 fell into the sea. If the question is the age of the captain, then you can deduce that he is 45-5 = 40 years old (equal to the number of sheep left).
On the other hand, someone said that a captain must be over 25 years old to obtain a license. Or even someone gave the answer of 16 because they thought that just … at such a young age he lacked experience, shedding 5 sheep at a time.
The solution to the “sheep’s head – captain’s tail” problem
In fact, the answer is “problem with incorrect facts“! Excellent teacher Pham Dinh Thuc – the father of the problem shared in an interview: The problem stands out
That’s a difficult problem that aims to improve students’ cognitive and sensing skills while practicing reading and thinking thoroughly before doing so.
The author deliberately violated to train students the habit of careful reading to distinguish what was given and what to find before undertaking a problem.
