First, primary school mathematics
Primary school mathematics is to teach children a series of knowledge about number, four operations, the calculation formula of figure and length, unit conversion and so on through textbooks, which lays a good mathematical foundation for junior high school and daily life calculation. Frieden Noel, a Dutch educator, said: "Mathematics comes from reality and must be rooted in reality and applied to reality."
Indeed, modern mathematics requires us to observe the world from a mathematical perspective and explain the world in mathematical language. Judging from the mathematics learning psychology of primary school students, the learning process of students is not a passive absorption process, but a reconstruction process based on existing knowledge and experience. Therefore, learning while doing and learning while playing will make children learn more actively.
Second, the specific content of primary school mathematics core literacy
Sense of number: it mainly refers to the intuitive perception of logarithm and quantity, the relationship between number and operation result, the ability to understand the meaning of number in real situations, and the ability to express the number of objects or the order of things with numbers.
Sense of quantity: Have an intuitive perception of the measurable attributes and size relationship of things, know the significance of measurement, and understand the necessity of unifying measurement units.
Symbol consciousness: able to understand and use symbols to express numbers, quantitative relations and changing laws; Knowing that symbols can be used for operation and reasoning, the conclusion is general.
Methods of Cultivating Core Literacy in Primary Mathematics Teaching
1. Carefully design teaching contents and activities.
Teachers should carefully design teaching content and activities according to students' age characteristics and cognitive level, combined with the content of teaching materials. Through lively and interesting teaching situations and practical activities, students' interest in learning and desire to explore are stimulated, and students can experience, feel and discover mathematics in the activities, thus cultivating their core literacy such as number sense and spatial concept.
2. Pay attention to students' independent inquiry and cooperative learning.
In primary school mathematics teaching, teachers should pay attention to students' independent inquiry and cooperative learning. By guiding students to observe, operate, experiment, guess, verify and other inquiry activities, students can actively participate in mathematics learning and cultivate their inquiry ability and innovative consciousness.
