In fact, many math problems on the market are seriously divorced from the reality of life. For the most famous example, chickens and rabbits are in the same cage. This problem does not come from real life at all. Which child has really seen a chicken and a rabbit in the same cage?
There is also the problem of trains meeting. How can the train run in the opposite direction? These topics are too unrealistic.
In the enlightenment stage, what children should really contact is: how many bus stops, how many minutes each stop, and how long does it take to get to school? Or it takes a few minutes to take the elevator from home to downstairs, which is a problem from life.
These questions not only make children sensitive to mathematics, but also stimulate their interest in mathematics.
