1, find a home for the graphic baby: develop children's understanding of graphics and correctly distinguish the difference between rectangles and squares. Cut out the shape of a small house with a foam board, paste a transparent plastic film around the house, and paste pictures of small animals holding graphics on the eaves. Use small building blocks to put plastic-sealed pictures with graphic shapes on the pictures, so as to stabilize the pictures and increase the fun of toys. By observing the physical pictures and classifying them according to their shapes, the children sent the little graphic babies home respectively.
2. Queuing: I can initially understand the neighboring number and master the neighboring number of numbers within "7". Can read Arabic numerals correctly. And numbers correspond to physical quantities one by one. Objects can be classified according to their characteristics, and the number of neighbors within 7 can be found according to the category. Teachers guide children to find the adjacent numbers within "7" according to the physical cards, and insert the tubular toys into the base in turn; According to the number of physical cards, digital cards correspond to them in turn, and tubular toys with digital cards are inserted. The teacher instructed the children to read Arabic numerals accurately.
3. Ladybug crawling: one-dimensional sorting can be carried out according to different colors or shapes of paper pieces. Main box: Draw the shape of ladybug with oily crayons, carve the gaps that can support children's one-dimensional sorting with wallpaper knife, and finally stick the finished colored paper on the carton with double-sided tape; Colored paper: Use red, yellow, blue and green colored paper commonly used by children to cut out patterns commonly used by children (such as circles, hearts and mushrooms). ) Put the cut paper into a plastic box with scissors.
4. Pave a road: guide children to discover the rules of sorting and sort them in one or two dimensions according to the rules. Take a clean foam board and put the small mushrooms in a beautiful little box. The back of the board is supported by hard objects, so that the foam board can stand upright. Cut out the picture, press it, stick it on the board, put it in a place where children can insert mushrooms with transparent hard molds, and then put several molds of mushrooms in a small box, so that children can classify mushrooms according to the color rules. Children refer to the sorting rule of the last path to help the little gray rabbit pave the mushroom road. Then according to this sorting rule, choose two mushroom colors you like to pave the way for the little black rabbit.
5. White rabbits grow mushrooms: distinguish the color and size of mushrooms; Mushrooms can be classified in two dimensions according to their colors and sizes. Make a meadow and create a certain situation with rabbits to stimulate children's interest in activities. Prepare colorful mushrooms of different sizes and colors for children. Children choose mushrooms of different sizes and colors for classification. Please carefully observe the regularity of their arrangement and continue to sort according to the regularity. For children with strong ability, ask them to design their own sorting methods, and kindergarten teachers with weak ability can use icons to prompt them.
6. Happy wheel identification 1- 10 digital card: the bitmap can be matched with the digital card. Make the digital card into the form of a big turntable and the bitmap into a trapezoid. The children will match the bitmap with the numbers. Children choose different numbers of idea maps. Please observe the total number of ideas carefully, and then insert the corresponding digital turntable according to the total number of ideas.
My son participated in the school tool exhibition.
Clocks, counters, rectangles, squares, parallelograms, etc.
The utility model relates to an educational demonstration appliance in the technical field of education, which is a demonstration appliance for computational mathematics.
At present, there are many kinds of primary school mathematics teaching tools and learning toolboxes, but these existing mathematics tools, especially learning toolboxes, are not matched with the primary school mathematics syllabus and teaching materials, which is divorced from the reality of primary school mathematics teaching. Although many students have it, it is rarely used effectively and cannot play its due role.
The purpose of this utility model is to provide a mathematics learning kit for the third grade of primary school, which effectively cooperates with the primary school mathematics teaching syllabus and various versions of teaching materials, is convenient to use, and is beneficial for students to learn and master the corresponding mathematics knowledge.
