2. Know and tell the up and down positions of nearby objects.
Seven. time

Middle shift:
Know yesterday, today and tomorrow.
Category:
Know morning, night, day and night.
2. What are the forms of classification activities?
The so-called "classification" is to divide a group of objects into several groups with the same attributes as * * * *, which is produced by seeking common ground. In fact, it is to divide a * * * into several subsets belonging to it.
In order to establish the consciousness of "class" and initially form the concept of * * * *, children need to go through a process of understanding the attributes of objects from the outside to the inside, and define and choose "similarity" or "difference" between objects. Markers always play an important role in classification activities.
As a symbol, "mark" is an abstract generalization of a certain feature of things, which can be used as a basis for seeking common ground or as a description of classification, that is, at the same time of seeking common ground, mark plays the role of prompting the object attributes stipulated by the standard of seeking common ground, and in classification, mark is the basis for classification. When children understand the meaning of a mark, they will use this mark to represent an item or a class of items. In this process, the abstract level and generalization ability of children's thinking can also be developed accordingly.
Therefore, the design of classification activities for small, medium and large classes can generally follow the order of seeking common ground in one standard, seeking common ground in several standards, seeking common ground in one classification and inserting labels one by one according to internal attributes, classification of quantitative relations and logical relations, hierarchical classification and classification from one angle to another.
3. What are the building skills that kindergarten primary school, middle school and large class should master respectively?
1. Construction skills of kindergarten small classes: (1) Enclosure: A space can be completely enclosed with different materials, and animals, cars and dolls are placed in the enclosed space, representing "zoo", "parking lot" and "dollhouse" respectively.
(2) Objects can be built by tiling, widening and lengthening. (3) It is excellent to try to build some objects by the method of base height, or to build three or more objects by the method of tiling and widening.
Most children learn to handle it carefully. 2. Construction skills to be mastered by the middle class in kindergarten: (1) Try to build an overhead fence with a high base on the basis of sticking bricks. (2) Different objects can be built by combining tiling and foundation height.
(3) It is excellent to try to build larger objects by overhead method, or to build three or more objects by combining tiling and building height. (4) Most people know how much to use. 3. The construction skills that kindergarten classes should master: (1) They can try to build different houses by overhead method on the basis of foundation height.
(2) Comprehensive use of skills such as tiling, extension, overhead and enclosure to build fences. (3) Try to construct different paths with skills such as curve tiling, straight tiling and extension.
(4) It is excellent to be able to build roofs for different houses, or to build four or more houses with different shapes. (5) Keep the site basically clean and tidy.
(during construction). Extended data:
The use of construction in cultural studies, social sciences and literary criticism refers to the construction of an analysis and reading system on existing texts, so that people can use an analytical context to disassemble the reasons and ideology behind those texts.
Therefore, construction is neither a fiction out of nothing, nor the only final decision to read texts, but a system found between texts. The opposite of construction is deconstruction, which focuses on the analysis and reading of various texts, and the construction focuses on the establishment of the system.
The word construction is the Chinese translation of English "construction". In Germany, Italy, Greece and the United States and other western countries, the word "structure" has experienced its emergence, development and change. It emphasizes the process of construction and pays attention to technology, structure, materials and forms of expression.
Construction is the logical expression of structure (force transfer relationship) and construction (corresponding arrangement of components). The content of construction, from architectural design to completion, not only conforms to the mechanical laws, but also follows the structural characteristics; At the same time, it also conforms to the aesthetic law that it should have from the perspective of artistic aesthetics; In addition, it can maintain the above characteristics during construction and implementation.
