a) Integer 1 Meaning of Integer: Natural numbers and 0 are both integers.

2 Natural Numbers:

When we count objects, we use them to express the number of objects ...... 1, 2, 3It's called a natural number.

There is not a single object, which is denoted by 0. 0 is also a natural number.

3 counting units.

Commonly used quantity relations.

1. The number of copies per copy The total number of copies The number of copies The number of copies per copy.

Multiples Multiples Multiples Multiples Multiples 1 Multiples 1 multiples.

3. Speed, time, distance, distance, speed, time, distance, time, speed.

4. Unit price, quantity, total price, total price, unit price, quantity, total price, quantity, unit price.

5. Work efficiency, working hours, total work, total work, work efficiency, working hours.

1 km = 1000 m 1 m = 10 dm 1 dm = 10 cm 1 m = 100 cm 1 cm = 10 mm.

Area Unit Conversion:

1 square kilometer = 100 hectares 1 hectare = 10,000 square meters 1 square meter = 100 square decimeters.

1 square decimeter = 100 square centimeters 1 square centimeter = 100 square millimeters.

Volume (volume) unit conversion:

1 cubic meter = 1000 cubic decimeters 1 cubic decimeter = 1000 cubic centimeters 1 cubic decimeter = 1 liter.

1 cubic centimeter = 1 milliliter 1 cubic meter = 1000 liters.

Weight unit conversion: 1 ton = 1000 kg 1 kg = 1000 g 1 kg = 1 kg.

RMB unit conversion: 1 yuan = 10 jiao 1 jiao = 10 cents 1 yuan = 100 cents.

Time Unit Conversion:

1 century = 100 years 1 year = 12 months (31 days) are: 1 3 5 7 8 10 December Small months (30 days) are: 4 6 9 November.

28 days in February in a common year, 29 days in a leap year 365 days in a common year, 366 days in a leap year 1 day = 24 hours.

1 hour = 60 minutes 1 minute = 60 seconds 1 hour = 3600 seconds.

1. Number and algebra: the understanding of numbers, the operation of numbers, formulas and equations, ratios and proportions.

2. Space and Graphics: Lines and Angles, Plane Graphics, Three-Dimensional Graphics, Graphics and Transformations, Graphics and Positions.

3. Statistics and possibility: measurement, statistics, and possibility.

4. Practice and comprehensive application: exploration rules, general compound application problems, typical application problems, fraction and percentage application problems, ratio and proportion problems, problem-solving strategies, and comprehensive application problems.

I think the knowledge points of primary school mathematics are summarized as follows:

1.The understanding of numbers: natural numbers, integers, fractions, decimals, positive numbers, negative numbers, zeros and other concepts.

2.Addition, subtraction, multiplication and division: the basic concepts and operation methods of addition, subtraction, multiplication and division, such as addition principle, subtraction principle, multiplication principle, division principle, etc.

3.Quantitative relationship: size relationship, how many brothers are related, comparative size, equality relationship, etc.

4.Fractions: the basic concepts of fractions, the simplification of fractions, the addition, subtraction, multiplication and division of fractions, the comparative size of fractions, etc.

5.Decimal: the basic concept of decimals, how to read decimals, the addition, subtraction, multiplication and division of decimals, the comparative size of decimals, etc.

6.Triangles: the basic concept of triangles, the classification of triangles, the properties of triangles, the area of triangles, etc.

7.Straight lines and angles: the basic concepts of straight lines, the basic concepts of angles, the classification of angles, the degrees of angles, the measurement of angles, etc.

9.Geometric figures: the basic general disturbance of plane figures, the classification of plane figures, the properties of plane figures, the area of plane figures, etc.

10.Time and calendar: the recognition of time, the calculation of time, the use of calendars, etc.

Primary school mathematics is a mathematics course that students learn in primary school, and I think it mainly includes the following knowledge points:

1.Understanding of numbers: the understanding and application of natural numbers, integers, fractions, decimals, etc.

2.Number operations: mastery and application of basic operations such as addition, subtraction, multiplication, and division.

3.Quantity relationship: the understanding and application of the size relationship, the number relationship, the comparison size, etc.

4.Geometry: the understanding and application of basic geometric concepts such as points, lines, surfaces, and volumes.

5.Properties of geometric figures: the properties and applications of geometric figures such as straight lines, angular buriers, triangles, quadrilaterals, etc.

6.Understanding and conversion of units of measurement such as time, length, weight, and volume.

7.Data statistics: the creation of charts and the analysis of data.

The above are the basic knowledge points of primary school mathematics, through which students can initially master mathematical thinking and methods, and lay a solid foundation for further learning.
