The contents of this textbook include the following contents: position and direction, divisor is the division of one digit, two digits are multiplied by two digits, the preliminary understanding of decimals, area, year, month and day, simple data analysis and averaging, solving problems with mathematics, wide angle of mathematics and mathematical activities.

Second, the main purpose of the book teaching requirements

1. Know the eight directions of east, south, west, north, northeast, northwest, southeast and southwest, and be able to identify the other seven directions with a given direction (east, south, west or north) and use these words to describe the direction of objects; Can read simple road maps and describe walking routes.

2. I will calculate the division of one digit divided by multiple digits, the multiplication of two digits, and estimate and check the corresponding multiplication and division methods.

3. The division quotient of a digit is integer ten, integer hundred and integer thousand, integer ten and integer hundred multiplied by integer ten, and two digits multiplied by integer ten and integer hundred (each product is less than ten).

4. Have a preliminary understanding of simple decimals (the decimal part does not exceed two digits), have a preliminary understanding of the meaning of decimals, can read and write decimals, have a preliminary understanding of the size of decimals, and can calculate the addition and subtraction of one decimal.

5. Understand the meaning of area. You can use your own units to estimate and measure the area of a graphic, experience and understand the area unit, and carry out simple unit conversion. Mastering the area formulas of rectangles and squares can correctly calculate the areas of rectangles and squares and estimate the areas of given rectangles and squares.

6, know the time unit year, month, day, and understand the relationship between them; Know the days of each month and the whole year; Knowing the 24-hour clock, I will use the 24-hour clock to express the time.

7. Understand the different forms of bar charts and learn simple data analysis; Understand the meaning of average and find the average of simple data; Further understand the role of statistics in real life.

8. Experience the process of finding, asking and solving problems in real life, understand the role of mathematics in daily life, and initially form the ability to solve problems by comprehensively applying mathematical knowledge.

9. Understand the idea of set and equivalent replacement, form the consciousness of discovering mathematics in life, and initially form the ability of observation, analysis and reasoning.

10, experience the fun of learning mathematics, improve the interest in learning mathematics, and establish confidence in learning mathematics well.

Third, the focus and difficulty of teaching

Teaching emphasis: orientation and direction, year, month and day, divisor is one-digit division, and two digits are multiplied by two digits.

Teaching difficulties: location confirmation, calculation and time calculation.

Fourthly, the analysis of students' situation.

There are two classes in grade three. Most students have a correct learning attitude, clear learning objectives, and are attentive in class. They can take the initiative to ask the teacher if they don't understand questions. Only a few students are not active enough ideologically. Most students in each class have a solid grasp of basic knowledge, accurate answers to questions, quick response, positive answers to questions in class, strong language expression ability, coherent speech, and some students have a poor foundation.

Verb (abbreviation of verb) measures to improve teaching quality

1. Focus on cultivating students' flexible computing ability and developing their sense of numbers.

2. Provide rich teaching content of space and graphics, pay attention to practice and exploration, and promote the development of students' space concept.

3. Combined with practical problems, teach simple data analysis and averaging, deepen students' understanding of the role of statistics, and gradually form statistical concepts.

4. Strengthen the teaching of problem-solving ability and cultivate students' comprehensive ability to solve problems with mathematical knowledge.

5. Infiltrate mathematical thinking methods step by step to cultivate students' mathematical thinking ability.

6. The cultivation of emotion, attitude and values permeates mathematics teaching, and stimulates students' interest and inner motivation with the charm of mathematics and the harvest of learning.
