Question 3: How many blocks is the primary school mathematics divided into? What does each block include? Primary school mathematics includes three blocks, one is number and algebra, the other is geometry and graphics, and the third is statistics and probability.
Numbers and algebra mainly include reading and writing methods of numbers (integers, decimals, fractions), rewriting of numbers (turning them into tens of thousands or hundreds of millions of numbers, seeking divisors, etc. ), comparison of numbers (comparison of integer, decimal and fractional sizes), and four operations (calculation rules, operation sequence, operation rules, etc.). ), and the measurement of quantities (quality, length, area, etc.).
Geometry and graphics include understanding graphics (the name of graphics, the names of various parts, characteristics, properties, the relationship between graphics, etc. ), observe objects, calculate the area of plane graphics, the surface area and volume of three-dimensional graphics, the movement (translation and rotation), position and direction of graphics, and so on.
Statistics and probability mainly include: statistical tables and charts (bar lines, sectors, broken lines, etc.). ) average mode, probability and so on.
Question 4: What is the content of primary school mathematics besides numbers? Classroom teaching is an art, which requires not only accurate content, exquisite form, exquisite methods, exquisite language, accurate guidance and precise integration, but also changeable, harmonious and smooth rhythm to schedule, so as to be like a beautiful movement, and every beating note makes people feel happy physically and mentally. Mathematics classroom teaching should also have rhythm. Moderate classroom rhythm can attract students' attention and keep their enthusiasm from beginning to end. Make the classroom teaching ups and downs, so as to easily and happily realize the teaching purpose and complete the teaching task. First, the optimization of mathematics classroom teaching rhythm can link all the teaching links in the teaching process and make the whole classroom interlocking. Teachers should replace single boring "perfusion" with comprehensive intelligent activities of various sensory coordination activities in teaching methods according to teaching contents, teaching tasks and objectives and students' basic conditions. In terms of methods, we should not only use limited verbal calculation, winning the red flag, driving the train, grabbing answers and other means, as well as teachers' short language and serious expression to create a tense classroom atmosphere, but also use storytelling, classroom exercises, humorous language and lively expressions to make students feel fresh and curious all the time, so that their thinking can be constantly adjusted and their attention can be more concentrated. In any lecture, students can easily remember the beginning, the end and any outstanding examples that stimulate their imagination. Frequent "state changes" make students' brains always in a state of excitement, which makes it possible for the classroom rhythm.
Question 5: What are the main types of mathematics learning in primary schools? One is calculation (including simple calculation, mixed calculation and simple calculation)
Second, application problems (including general application problems and equation application problems). )
Among them, calculation is to examine students' basic knowledge, and the application is flexible.
Question 6: What does primary school mathematics ability include? To know a good math class, we should pay attention to two points: First, pay attention to students and proceed from their reality.
Paying attention to students' emotional needs and cognitive needs, paying attention to students' existing knowledge base and life experience, is
The necessary foundation of a successful class. Second, attach importance to mathematics: grasp the essence of mathematics for teaching and attach importance to numbers.
The infiltration of learning thinking method allows students to experience mathematics in the process of observation, operation, reasoning and verification.
Let students really experience mathematics, enjoy learning and love learning mathematics in the process of learning.
A good math class should not have the complex of "showing off", but should advocate "concise, profound, fresh and heavy" teaching.
Style, display thinking power, pay attention to mathematical methods, embody the soul of mathematics class, and make mathematics class have "mathematical taste"
! The teacher's "leave room for playing dumb" is also a teaching wisdom and method.
Question 7: What is the design idea of the main content of the new curriculum standard of primary school mathematics? (1) In order to reflect the integrity of the mathematics curriculum in the compulsory education stage, the content of the new primary school mathematics curriculum standard "Full-time compulsory education mathematics curriculum standard (experimental draft)" (hereinafter referred to as the "standard") has been comprehensively considered for nine years; Meanwhile, according to
