This textbook includes the following contents: addition and subtraction within 10,000, a factor is the multiplication of single digits, a divisor is the division of single digits, the understanding of hours, minutes and seconds, mixed operations and two-step application problems, rectangles, squares and parallelograms.
The addition and subtraction within 10 thousand in this textbook focuses on the addition and subtraction of three or four digits. At this stage, students have mastered the addition and subtraction of three or four digits, and when they encounter more addition and subtraction of digits in the future, they can make analogy.
Multiplication and division means that students master multiplication tables and division within tables, and teach one-factor multiplication and one-factor division.
Mixed operation is to teach some relatively easy three-step operation sequences on the basis of consolidating the operation sequence of two-step problems.
In the measurement of quantity, this volume of teaching initially established the concept of time for students and understood the time unit: city, minute and second.
In the aspect of geometry, let students know parallelogram, rectangle and square, and calculate their perimeters, so as to continue to develop students' concept of space.
In solving application problems, some application problems with known three conditions are appropriately expanded on the basis of the previous book, and students can learn to solve two-step application problems with two conditions.
In terms of practical activities, this book is the same as the previous books. On the one hand, when teaching new knowledge, arrange a lot of practical activities to let students understand the relationship between mathematical knowledge and real life. Experience the formation process of mathematical concepts through hands-on operation. On the other hand, at the end of some units, the content of practical activities is specially arranged. By solving mathematical problems in activities, students can feel, experience and understand mathematics.
The mathematical knowledge in this book strengthens the cultivation of ability and good study habits. Initially cultivate the ability of abstract generalization; Initially cultivate analytical and comprehensive abilities; Initially cultivate the ability of judgment and reasoning; Guide students to explore the law; Initially cultivate the flexibility and agility of thinking; Pay attention to cultivating students' interest in learning and good study habits.
