The teaching objective of this unit is: 1. Let the students know the counting units "one", "ten" and "hundred" and count them correctly.

The number of objects within 100, knowing that the number within 100 is composed of ten and one; Know the unit, decimal places and hundreds, know the meaning of the numbers on the unit, decimal places and hundreds, and be able to read and write the numbers within 100 correctly; Master the numerical order within 100, and compare the numerical sizes within 100. 2. Make students know the names of each part in the addition and subtraction formula, and correctly and skillfully calculate the integer plus one digit and the corresponding subtraction. 3. Make students understand the meaning of numbers within 100, explore the composition method of numbers within 100, and compare the sizes of numbers within 100, so as to understand the abstract process of numbers, develop the sense of numbers and enhance the consciousness of cooperation and communication with others. 4. Make students feel the connection between numbers and life in the activities of expressing things in daily life with numbers within 100, and make simple estimation and communication, so as to cultivate the consciousness of observing things around them and daily life from a mathematical point of view. Xx: The focus of this unit is on the meaning and reading and writing methods of numbers within 100. This is partly because of the numbers.

The knowledge involved in reading and writing methods, such as meaning, number concept and composition method, is the premise and foundation for students to understand the order and size of numbers and form the corresponding sense of numbers; On the other hand, it also has an important influence on students' understanding of larger numbers in the future. The difficulty in this unit teaching is to let students use "many", "few", "many" and "few" to describe the relationship between numbers. Because the correct use of the size relationship described in the above words requires students not only to have a good sense of numbers, but also to properly grasp the relative size of numbers in specific situations and make reasonable and flexible choices. Xx: according to the learning characteristics of first-year students, construct the unit knowledge structure. This unit has a large amount of teaching knowledge, and the textbook attaches great importance to the optimization of the unit knowledge structure. As far as the meaning and reading and writing of numbers are concerned, first, by putting two numbers with a stick and counting them with the help of sticks, students can initially perceive the composition characteristics of the two numbers and the basic counting method of "from 10 to 1", and guide students to understand the numbers and order represented by numbers within 100. On this basis, with the help of counters, teaching students to read and write numbers within 100 is helpful for students to further understand the composition of two-digit numbers and clarify the names of related numbers. After that, the textbook immediately arranges the whole ten plus one numbers and the corresponding subtraction oral calculation to guide students to explore from the perspective of the composition of numbers.
