Hebei Education Publishing House, the second grade mathematics teaching plan, the first part of the first part of the student situation analysis;
Grade two students have developed good study habits in the past year. They can think positively, speak actively and finish their homework on time. Most students can skillfully calculate the addition and subtraction within 100, and can ask and solve simple problems. Location, graphics, statistics and other knowledge. You can also master it well. Individual students have not reached the correct and fast calculation, so we should strengthen counseling in the future.
Second, teaching material analysis:
This textbook includes the following contents: division in tables, understanding of numbers within 10,000, simple addition and subtraction within 10,000, graphs and transformations, grams and kilograms, statistics, discovering laws, solving problems with mathematics and mathematical practice activities. The key content of this textbook is division in tables, understanding of numbers within 10,000, and solving problems with mathematics.
The arrangement of division in the table embodies two characteristics. First, on the basis that students have mastered multiplication in tables, the teaching materials focus on the teaching of division in tables. Second, there is no clear distinction? Divide it equally? And then what? Include and divide? In the average operation activity, let students experience and feel two different life prototypes (divide 15 apples into 5 parts on average; 24 people charter a boat, each boat is limited to 4 people), so that students can understand the meaning of division.
The understanding of numbers within 10 thousand changed the original arrangement structure. Teach the numbers within 1000 first, and then teach the numbers within 10,000, and the number sequence table and divisor appear. The arrangement of addition and subtraction within 10 thousand yuan has transitional characteristics: on the basis of addition and subtraction within 100 yuan in the previous book, two digits are added and subtracted; Teach three-digit (hundreds of dozens) pen arithmetic addition and subtraction to prepare for further learning multi-digit addition and subtraction. This unit also combines hundreds of teaching contents of addition and subtraction to arrange estimation, so that students can further learn to use estimation to solve practical problems according to specific situations.
Solving problems mainly includes two aspects. First, the problem-solving teaching unit is arranged, and students' lively extracurricular activities are used as materials to show all kinds of problems encountered by students in practical activities; Second, combined with the teaching of division in tables and addition and subtraction of numbers within ten thousand, the relevant contents of solving problems are arranged in time, so that students can learn to solve some simple practical problems with their own mathematical knowledge after mastering some knowledge of numbers and calculation.
In terms of space and graphics, this textbook arranges a chapter on graphics and transformation, including? Acute angle and obtuse angle translation and rotation? . Compared with the original textbook, acute and obtuse angles? Understanding is obviously ahead of time. Translation and rotation? This is a new addition. In the measurement of quantity, grams and kilograms are taught, so that students can feel grams and kilograms in specific life situations through independent exploration and practical activities, and initially establish a quality concept. In the aspect of statistical knowledge, let students further study the significance of statistics, learn simple data and sorting methods, and know bar statistical charts and simple composite statistical tables. Is this textbook also arranged? Looking for patterns? The teaching content of this course guides students to explore the arrangement law of figures and numbers through observation, guessing, experiment and reasoning. Not only make students know that the regular arrangement of things in real life contains mathematical knowledge, but also cultivate students' observation ability, calculation ability and inductive reasoning ability, discover and appreciate the beauty of mathematics, and use mathematics to create the consciousness of beauty.
Third, the teaching objectives:
1, combined with the specific situation in real life, so that students can understand the basic meaning of mathematical problems, learn to solve problems by two-step calculation, and know the role of brackets. Cultivate students' good habits such as careful observation and independent thinking, and initially cultivate students' ability to find, ask and solve problems in real life.
2. Let students understand the meaning of division in a specific situation, read and write the division formula, and know the names of each part of the division formula. Make students know the relationship between multiplication and division, and skillfully use multiplication formula to find quotient. Enable students to solve some simple practical problems according to the meaning of division. Combined with teaching, educate students to love learning, labor and nature. Cultivate students' good study habits such as careful observation and independent thinking.
3. Make students know right angle, acute angle and obtuse angle; Let students perceive translation and rotation with examples; Will draw a simple figure on the grid paper after horizontal and vertical translation; The teaching thought method of initial infiltration and transformation.
4. Let the students experience it by themselves. 9 The process of seeking quotient by multiplication formula, and master the general method of seeking quotient by multiplication formula; Make students learn to apply multiplication and division comprehensively to solve simple or slightly complicated practical problems; In the process of solving problems, let students try to use the methods of analysis, reasoning and transformation.
5. Let student administrators experience the process and function of counting; Capable people can read and write numbers within 10 thousand, knowing that these numbers are composed of thousands, hundreds, tens and ones; Symbols can be used to describe the size of numbers within 10 thousand; Be able to name each number and identify the meaning of each number; Let the students feel the meaning of large numbers, know the divisor and make an estimate according to the actual situation. Can calculate whole hundred, add and subtract whole thousand; Let students further learn to describe things in life with concrete numbers, and communicate with others, cultivate their interest and self-confidence in learning mathematics, and gradually develop their sense of numbers.
6. In specific life situations, let students feel and know the unit grams and kilograms of quality, and initially establish the concepts of 1g and 1kg, knowing that1kg =1000g; Make students know how to weigh objects and make simple calculations; On the basis of establishing the concept of quality, cultivate students' consciousness of estimating the quality of objects.
7. Enable students to correctly calculate the addition and subtraction of two digits, and correctly calculate the addition and subtraction of hundreds and dozens; Enable students to estimate by addition and subtraction in combination with specific conditions, and cultivate estimation consciousness; Cultivate students' awareness of choosing appropriate methods to solve practical problems according to specific situations and experience the diversity of problem-solving strategies.
8. Make students experience the process of data collection, sorting, description and analysis, understand the significance of statistics, and collect and sort out data by simple methods; Make students know bar chart and simple compound statistics, ask and answer simple questions according to the data in the statistical chart, and awaken simple analysis; Through the investigation of interesting cases in real life around us, we can stimulate students' interest in learning and cultivate their sense of cooperation and innovative spirit.
9. Through observation, guessing, experiment, reasoning and other activities, students can discover the arrangement law of figures and numbers; Cultivate students' ability of observation, operation and inductive reasoning; Cultivate students' awareness of discovering and appreciating the beauty of mathematics, create the awareness of beauty with mathematics, and let students know that the regular arrangement of things in life contains mathematical knowledge.
