Teaching Design of Mathematics Core Literacy
?
The primary school mathematics teaching design based on the cultivation of students' mathematics core literacy is based on the significance of the cultivation of core literacy, and the connotation of core literacy should be briefly analyzed. The optimization of primary school mathematics teaching design based on the cultivation of students' mathematics core literacy requires teachers to study the textbooks carefully and make full use of the core literacy resources contained in the textbooks. Create situations to activate students' awareness of cultivating core literacy with the help of life situations and problem situations; Strengthen experience in hands-on practice in and out of class, and develop students' core literacy. ?
?
? With the deepening of curriculum reform, core literacy has become a high-frequency word that teachers generally pay attention to, and people regard core literacy as the DNA of basic education. Primary school mathematics education, as the initial stage of students' mathematics learning, plays a fundamental role in the development of students' comprehensive mathematics quality. In the new era, in order to further improve the efficiency of mathematics classroom teaching and promote the development of students' mathematical ability, teachers should reconstruct primary school mathematics teaching based on the cultivation of students' core literacy to realize students' all-round and sustainable development.
?
The connotation of primary school students' mathematical core literacy refers to the mathematical knowledge, mathematical thought and mathematical consciousness formed by students in the process of mathematics learning for their own development and adaptation to social needs, and is the core connotation of students' comprehensive literacy. The curriculum standard defines the general goal of mathematics teaching curriculum as four dimensions: mathematics knowledge and skills, mathematics thinking method, mathematics application consciousness and mathematics attitude spirit. From these four dimensions, the core literacy is divided into the following two levels: mathematical operation ability, intuitive imagination ability, number sense, mathematical abstraction ability, logical reasoning ability, mathematical modeling ability, symbol consciousness, tool use ability, flexibility and adaptability, mathematics learning interest, dialectical thinking, innovation consciousness and so on. , and form a corresponding relationship with the curriculum objectives. ?

Intensive reading of textbooks and deep excavation of core literacy textbooks are effective carriers of primary school mathematics teaching and support for the development of students' core literacy. The compiling process of teaching materials embodies the efforts and wisdom of the writers, which is typical and scientific. Therefore, primary school mathematics teachers should read textbooks intensively, dig deep into the core literacy contained in textbooks, and give full play to the effectiveness of textbook carriers. The study of teaching materials should be thorough and meticulous, break the current situation of seeking other things without teaching materials, make full use of every question, every picture and every paragraph of the teaching materials, seek the connection between all parts of the teaching materials, dig out the core literacy contained in the teaching materials, and effectively develop students' core literacy with the help of the teaching materials. For example, the second volume of the fourth grade? Calculator? In this part, the textbooks are ingenious when they are arranged. First of all, the textbook is about the ancient trees in Mount Tai. Statistics on the number of ancient trees in Mount Tai? Stealing tickets is not only a matter of time, but also a matter of time. Content, guide students to think. What questions can I ask? On this basis, organize students to carry out? Cooperative learning? An example is given, and two calculation methods are used to calculate, one is vertical operation, the other is calculation with calculator, and the advantages of calculator are obtained. Finally, the composition of the calculator is introduced with the help of charts. This textbook design starts with the ancient trees of Mount Tai that students are interested in, then guides students to compare them, and finally highlights the key points of calculator teaching. This not only helps to stimulate students' interest in learning, but also conforms to the cognitive law from perceptual to rational. It also contains rich core literacy, which can cultivate students' symbol consciousness, graphic conversion ability and tool use ability, and help develop students' core literacy in mathematics.

Creating situations, activating students' core literacy and cultivating consciousness mathematics does not exist in isolation, but often depends on specific situations. The design of primary school mathematics teaching based on the cultivation of students' core literacy requires us to attach importance to creating situations, change the traditional mathematics teaching mode, stop unilaterally exporting knowledge and put mathematics knowledge in vivid situations. This not only helps to stimulate students' interest in learning, but also expands the path for the development of students' mathematics core literacy, so that students can not only acquire knowledge, but also learn to use knowledge according to situations, and cultivate students' abstract thinking ability from situations. Creating situations should pay attention to art, and teachers should be good at creating life-oriented situations and building a bridge between life and mathematics. We should be good at creating problem situations, and stimulate students' curiosity and problem consciousness through problem situations, so as to guide students to wander in the depths of mathematics classroom. ? Like what? Understanding of millimeter, decimeter and kilometer? First, I quoted the Monkey King as a topic to create a situation. There is an artifact in the Monkey King. Do the children know?
?
What's amazing about this golden hoop? The answer can be changed, longer or shorter. ) Once the Monkey King and Erlang God were fighting, the Monkey King changed the golden cudgel into 5mm, 5mm and 5km respectively, and asked Erlang God how long these three lengths were? Through this lesson, can children use their brains to help a group of Erlang gods? Then show it with a stick, measure it with a ruler, and list objects with similar lengths in life. The purpose of this link design is to stimulate children's interest in learning by using fairy tales that children are interested in, so that children will have the desire to explore what they want to learn and stimulate the awareness of learning subjects; On this basis, the length units of 5 mm, 5 decimeter and 5 km are introduced to stimulate children's curiosity and make them want to explore. Finally, with the help of sticks, children can complete the cognitive process from perceptual to rational, thus promoting the development of children's core literacy such as modeling ability and tool use ability.

Strengthening experience and developing core literacy in practical application Mathematics is an applied subject, which needs to gain true knowledge in practice and continuously improve practical application ability. The primary school mathematics teaching design based on the cultivation of students' mathematics core literacy should focus on strengthening students' learning experience and developing students' core literacy in rich practical applications. First of all, teachers should make full use of classroom learning time, create practical opportunities for students, let students do it, and get personal feelings, so as to strengthen students' perceptual knowledge and then rise to rational knowledge; Secondly, teachers should guide students to practice after class. Mathematics class hours are limited, and students' practical ability cannot be fully developed due to the constraints of teaching environment and teaching conditions. Extracurricular practice helps to expand students' learning channels, enable students to test and apply what they have learned in extracurricular practice, and promote the development of students' core literacy. Like what? Symmetry, translation and rotation? If this part of the content is taught only in theory, the effect is obviously poor, it is difficult to stimulate students' interest in learning, which is not conducive to the cultivation of students' core literacy. Therefore, I decided to adopt the experiential teaching method and design a series of hands-on practice links, so that students can fold and cut symmetrical figures by themselves, thus gaining an intuitive understanding; Pass again? Move, swing, swing, draw a picture? And then what? Do it. And so on, constantly strengthen students' understanding of concepts such as symmetry, translation and rotation, so that students can acquire knowledge in hands-on practice, and their core literacy such as intuitive imagination and mathematical abstraction ability has been greatly developed; After class, by looking for symmetry, translation and rotation in life, we can achieve the purpose of consolidating and strengthening, and promote the transformation of students' mathematical knowledge into core literacy.

Three. Conclusion In a word, cultivating students' mathematics core literacy is the inevitable direction of primary school mathematics teaching, and mathematics teachers should raise it to a new height. Based on the cultivation perspective of students' core literacy, we constantly interpret the connotation of core literacy in practice, seek effective ways to cultivate students' core literacy in mathematics, lay the foundation for primary school students' lifelong mathematics learning, realize the sustainable development of primary school students, and make the mathematics classroom exude lasting vitality. ?

Primary school mathematics teaching design to cultivate core literacy?
With the deepening of curriculum reform, the research and discussion on core literacy has become an important topic in the field of education, and core literacy has also become a high-frequency word that teachers generally pay attention to. People pay more and more attention to the cultivation of students' quality and the cultivation of students' core literacy. So how to cultivate students' core literacy in the classroom?
?
First, establish an educational concept centered on cultivating the core literacy of mathematics.
?
Is core literacy what experts say? DNA of curriculum development? It is the concretization and manifestation of comprehensively implementing quality education and implementing the fundamental task of moral education. Experts pointed out: In? A well-rounded person? Among the core values, students should have the qualities of humanistic heritage, scientific spirit, learning to learn, healthy life, responsibility and practical innovation, which is also the requirement of the country for future talent development. Mathematics core literacy is the comprehensive ability that mathematics learners should achieve in learning mathematics. The new curriculum standard clearly puts forward the core qualities of 10 mathematics, that is, number sense, symbol sense, space sense, intuitive geometry, data analysis sense, calculation ability, reasoning ability, model thinking, application consciousness and innovation consciousness. Core literacy embodies the essence and thought of mathematics, which is formed in the process of mathematics learning and is comprehensive, phased and persistent. Mathematics core literacy is directly related to the goal and content of mathematics curriculum, which is of great significance and value for understanding the essence of mathematics, designing mathematics teaching and carrying out mathematics evaluation.
?
After understanding the meaning and relationship between core literacy and mathematical core literacy, we once again set up the education and teaching concept that teachers take cultivating students' mathematical core literacy as the core. On the one hand, we can strengthen teachers' understanding of? Core literacy? Pay attention to teaching ideas and improve teachers' subjective initiative to update teaching ideas; On the other hand, we can organize study and training, special lectures and so on. Core literacy? A deep understanding of teaching helps teachers to understand? Core literacy? The importance, significance, purpose and training approach of the new teaching method, so that teachers can combine their own reality, innovate teaching methods, improve teaching effect and train students? Core literacy? Purpose.
?
Second, design primary school mathematics classroom teaching based on the development of students' core literacy.
?
(A) intensive reading of textbooks, teaching design around the core literacy of mathematics.
?
Textbooks are the effective carrier of teachers' teaching and the foundation of students' core literacy development. The compilation process of teaching materials embodies the efforts and wisdom of editors, and is also the result of repeated scrutiny and argumentation by editors, which is typical and scientific. Therefore, primary school mathematics teachers should intensively read textbooks, learn new curriculum standards at the same time, combine textbooks with curriculum standards, thoroughly scrutinize and excavate the core literacy contained in textbooks, and give full play to the carrier efficiency of textbooks. The study of teaching materials should be thorough and meticulous, and we should make full use of every theme situation, dialogue of each group of characters, every question, every hint and so on. According to the requirements of the new curriculum standard for different stages of mathematics core literacy, the knowledge goal, ability goal and emotional attitude goal of this class are set, appropriate teaching methods are selected, different forms of activity carriers are used to stimulate students' interest in learning, and the core literacy of students is effectively cultivated with the help of teaching materials.
?
Like grade three? What is the meaning of decimals? In teaching, the teacher first designs a specific unit teaching, and uses the relationship between yuan, angle, minute, meter, decimeter and centimeter to get one tenth of the score, that is, a fraction of one tenth. Redesign the teaching without unit: divide the square into ten equally, take seven of them and express them with decimal 0.7, and then summarize the abstract text: a few tenths of a score can be expressed with a decimal, and conversely, a decimal can also be expressed with a few tenths of a score. In this way, students' sense of numbers, reasoning ability and abstract thinking ability are cultivated, which is conducive to the development of students' core literacy.
?
(2) Design the links of students' autonomous learning and cultivate students' subjective initiative.
?
Actively create different situations to stimulate students' interest in learning, so that students can ask, analyze and solve problems according to different situations, and at the same time pay attention to designing the links of students' autonomous learning, so that students can have enough time to think and discuss independently, thus cultivating students' ability to solve problems and cultivating students' subjective initiative.
?
For example, teaching the second volume of the third grade? Area and area unit? In the first class, how to compare the sizes of two rectangular cardboard (the teacher holds two rectangular cardboard with different colors), students will think positively according to the cardboard, and some will answer with overlapping method and cutting method, but the effect is not ideal. The teacher leads out the measurement standard step by step and borrows different learning tools: small disk, small square and small rectangle. Ask the students to cooperate in groups, discuss which standard to choose for the test, and practice. Finally, according to everyone's cooperative practice, it is concluded that the area units must be unified. Students' cooperative learning and independent exploration have gained the importance of unified area units, stimulated students' interest in learning, and enabled students to find problems, think about problems and analyze problems in practice until they solved them, thus giving full play to students' subjective initiative.
?
(3) Provide hands-on opportunities to cultivate students' scientific practice and innovative spirit.
?
Mathematics is an applied subject. Due to the limited classroom time and teaching environment and conditions, students' practical ability cannot be fully exercised and developed, which requires math teachers to create more hands-on activities and opportunities to cultivate students' scientific practical spirit and innovative spirit. For example, teaching the second volume of the third grade? Area and area unit? In the first class, in order to let students understand the importance of unified area units, the teacher designed a group to cooperate and began to choose school tools (circle, square and rectangle) for pendulum test. The conclusion is that only the same school tools can be used to compare sizes, and the square is the most convenient. Let students draw scientific conclusions in practice, develop students' thinking in hands-on operation, and cultivate students' scientific practice spirit and innovative spirit.
?
In short, teachers should establish the educational and teaching concept of cultivating students' core literacy, fully understand the relationship between core literacy and primary school mathematics core literacy, intensively read textbooks, dig deep into textbooks according to the requirements of new curriculum standards for mathematics core literacy, design classroom teaching, and cultivate and develop students' core literacy.
