Mathematics teaching content of all age classes The above content and scope should be appropriately arranged for all age classes according to the development level of children's basic mathematics concepts in order to implement: 1. Perceptual aggregation class: 1. According to the example and explanation, separate a group of objects from a pile of objects. 2. Classify objects according to certain characteristics (color, size, length, shape, name, etc.). Distinguish and say "1" and "many" and understand their relationship. 4. Learn to correspond and compare more, less and the same number of two groups of objects without counting: 1. Classify objects according to a certain feature (such as height, thickness, thickness and weight). 2. Classify according to the number of objects. Big class: 1. Classification and free classification according to two characteristics of objects. 2. Understand the relationship between class and subclass, whole and part in the process of classification. Second, the number of subclasses within 10: 1. Hands and mouth always count objects within 4. 2. Take things by number (within 4): 1. Accurately count objects within 10. 2. Understand the relationship between "1" and "1" in two adjacent numbers within 10. 3. Understand the conservation of numbers within 10. 4. Know the ordinal number within 10. 5. Read Arabic numerals within 10. Big class: 1. Learn to count down, pick up and count in groups. 2. Understand the relationship between three adjacent numbers and the arithmetic relationship of natural sequence within 10. 3. Write Arabic numerals within 10 correctly. 4. Learn the composition of numbers within 10, and understand the equality, complement and exchange relationship between total and partial numbers. 3. Add or subtract small classes within 1 0: no middle class: no large class:1. Learn to solve and write simple oral application problems (sum, remainder). 2. Learn addition and subtraction with the knowledge of the composition of numbers. 4. Knowledge subcategory of quantity: 1. Compare sizes and classify by size. 2. Use your hands and mouth to count objects within 3, and feel the formation of numbers. 3. Objects with a count of less than 4 perceive the middle class: 1. Compare two objects with different thickness, thickness and weight. 2. Find an equal number of objects from several objects. 3. According to the difference of the quantity and number of objects, the positive and negative sorting is carried out within 5. Big class: 1. Compare two objects of different sizes, lengths and heights. 2. Find and say the largest and smallest of the five objects. 3. According to the external characteristics of objects (such as color and shape) or the differences in quantity (such as size, length and height), the three special objects are sorted positively. 5. Geometry class: 1. Know circles, triangles and squares. Can take out pictures according to their names and say their names. Middle shift: 1. Know rectangle, ellipse and trapezoid. 2. According to the number of angles and edges (shape conservation) of a plane figure, figures with different sizes, colors and placement positions can be correctly identified. 3. Understand the simple relationship between plane graphics. Big class: 1. Know circles, triangles and squares. Can take out pictures according to their names and say their names. 6. Spatial orientation subclass: 1. Distinguish the upper and lower directions with oneself as the center. 2. Know and tell the up and down positions of nearby objects. Middle shift: 1. Take yourself as the center and distinguish the front and back directions. 2. Distinguish the front and rear directions with the object as the center. 3. Will move in the specified direction (up and down, back and forth). Big class: 1 ... distinguish the up and down directions with itself as the center. 2. Know and tell the up and down positions of nearby objects. Seven, time small classroom: know morning, evening, day and night. Middle class: Know yesterday, today and tomorrow. Big class: Know morning, evening, day and night.
