? The word "core literacy" is the first time I have seen it in a book. What exactly is "core literacy"? With questions and curiosity, I started this week's reading task.

? Teacher Bu said that core literacy refers to "the necessary character and key ability that students should have to meet the needs of lifelong development and social development". Subject teaching should prepare "pump" and "paddle" for students' growth, so that students can have inexhaustible motivation in their future lives.

? 1. Growth Mathematics highlights the value connotation of mathematics core literacy from three aspects.

1. Mathematical growth will highlight the goal of mathematical literacy.

To tell the truth, there is still little attention to students' mathematical literacy in daily teaching, which may be the reason why many students are tired of learning mathematics now. I hope that this situation can be gradually changed by reading and learning the idea of growth mathematics and applying it to my own teaching.

2. Mathematical growth will highlight the inherent characteristics of mathematical literacy. Mathematical literacy is the sum of basic mathematical knowledge and problem-solving ability acquired by people through their own practice and cognitive activities.

3. Growing mathematics will highlight the cultural examination of mathematical literacy.

In the final analysis, mathematical literacy is about the core literacy that people must have in their development.

Second, the realization path of mathematical literacy.

1. Enhance students' mathematical awareness through mathematical abstract activities, and improve students' literacy of observing the world from a mathematical perspective. The article points out that the study of similar items has made me shine. It turns out that similar items can be studied like this! Let yourself really want to have an impulse to practice.

2. Develop students' mathematical core through mathematical reasoning activities and improve students' quality of thinking about the world with mathematical thinking.

3. Exercise students' mathematical expression ability through mathematical modeling activities, and improve students' quality of describing the world in mathematical language.

Mathematical modeling is seldom used in our own teaching. For example, when reviewing papers recently, students made many mistakes about square roots. The problem of solving equations like the following actually belongs to the problem of square root. A positive number 9\4 has two square roots, but many students take it for granted that there is only one positive number and miss the negative number! The other is holistic mathematical thinking. Don't expand the formula on the left, but you can't.
