The third grade mathematics teaching plan of the previous period in 2019

First, the textbook analysis:
The teaching content of this book includes the following contents: Divisor is a division of one digit, two digits by two digits, initial understanding of decimals, position and direction, area, year, month, day, simple data analysis and The average number is solved mathematically, math wide angle and mathematical practice activities.
Divisor is a one-digit division, two-digit by two digits, area and simple data analysis and average are the key teaching content of this book.
In terms of numbers and calculations, this booklet arranges the divisor to be a one-digit division, a two-digit by two-digit number, and a preliminary understanding of the decimal. This part of multiplication and division calculation is still the basic knowledge and basic skills that primary school students should master and form, and is an important basis for further study and calculation. For example, to divide a multi-digit number by two digits, the step of finding a quotient is basically the same as the step of dividing by a single digit; for example, a two-digit by two-digit number is a necessary basis for learning fractional multiplication.
The initial understanding of the introduction of decimals from this volume is relatively simple. At this time, students often encounter or use the knowledge and problems related to decimals in their daily life. This part of knowledge learning can expand the scope of solving practical problems with mathematics, improve students' ability to solve problems, and also enable students to learn initially. Simple decimals are expressed and communicated to further develop the sense of number and to pave the way for further systematic learning of decimals and decimals.
In terms of space and graphics, this booklet arranges two units of position, direction and area. This is the other two key teaching contents of this book, which provides rich materials for developing students' space concept. Through the study of these contents, students can initially form the ability to identify the direction, express and the direction in which the object is communicated. Through realistic mathematics activities, students will be able to gain experience in inquiry learning, explore and understand the necessity of introducing a unified area unit, understand area units, master the rectangular and square area formulas, and further promote the development of space concepts.
In terms of the measurement of quantity, this volume further expands the scope of measurement knowledge. In addition to the recognition of area units, it also arranges the time, method of understanding the larger time units, year, month, day and 24 o'clock. The teaching of these contents can further develop students' spatial concepts and time concepts, and cultivate students' awareness and ability to estimate the size and duration of the area through practical operations and specific experiences.
In terms of statistical knowledge, this booklet allows students to initially learn simple data analysis and averages. The textbook introduces students to two different forms of bar chart, allowing students to use the existing knowledge to learn to look at these two charts, and to learn simple data analysis; to learn the meaning of the mean and the simple average The method, the initial understanding of the meaning of the average and the actual application, further understand the role of statistics in real life.
In terms of solving problems with mathematics, the textbook arranges a unit on the one hand, which specializes in teaching and solving the simple problems in life by using the multiplication and division method learned. On the other hand, the teaching content of “mathematical wide angle” is arranged to guide students through observation. , guessing, experimenting, reasoning and other activities to learn simple collection ideas and equal substitution ideas, and can apply sets and equal substitution ideas to solve some simple problems, cultivate students' ability to observe, analyze and reason, cultivate them Explore the interest and discovery of mathematical problems and appreciate the awareness of mathematical beauty.
According to the mathematics knowledge and life experience that students have learned, this booklet arranges two mathematics practice activities, allowing students to use the knowledge they have learned to solve problems through the group's collaborative inquiry activities or activities with realistic background, and to experience the fun and mathematics of exploration. The actual application of the experience, the use of mathematical pleasure, training students' mathematical awareness and practical ability.
Teaching objectives enable students to:
1. It will calculate the multiplication of a single digit in addition to multiple digits, multiplication by two digits and two digits, and will perform corresponding multiplication, division estimation and checking.
2. The number of divisions is one tenth, one hundredth, and one thousand. The whole ten, the whole hundred are multiplied by ten, and the two digits are multiplied by ten or hundreds.
3. Initially understand the simple decimals, initially know the meaning of the decimals, read and write decimals, and initially understand the size of the decimals, and calculate the addition and subtraction of a decimal.
