Based on Problem Situation Creation, Students Cultivate Students' Core Mathematical Literacy

What mathematical literacy refers to, the first thing to understand is that mathematics requires very rigorous subjects, definitions, practical operations, logical proofs, and so on. Many aspects require you to have a careful thinking and a rigorous attitude. Learn mathematics to learn to learn to repeat three, the "anti-three" here is not as simple as changing the number of the same problem during the student period, but to link the knowledge learned before, after solid foundation, to try to use new knowledge to solve other problems, to understand the scope of application of this knowledge, what reproduction and change. Formulas, theorems, have to be deduced several times by themselves, understand, and then experiment with extreme conditions to see what conditions it is tried. This is much slower than memorizing by rote, but it will be more like a fish in the water and easy to use later.
