2. The teacher introduced the magic box to magic through a short story.
Last night, when the teacher was about to go to bed, the phone suddenly rang. The teacher picked up the phone and heard that my dinosaur brother called me. Brother dinosaur told me that this magic box can be exchanged for many small gifts and many delicious things. I heard it was great, so I thought if I changed a lot of delicious food, I would share it with the children in Class Three. But when the teacher changes it, you must let the children say loudly that 123 can be changed into gifts!
A rectangular gift box was created by magic, and then the teacher asked, Look, children, this is a gift box. What will be in this gift box? What can it hold? Through children's discussion, the teacher prompts the shape of the gift box, and then guides children to observe and understand the characteristics of a rectangle. A rectangle has four corners and four sides, which are equal up and down, equal in length, equal in left and right, and equal in length. Then the teacher asked the children, who wants a present? The teacher asked the best child to open the gift box (at this time, the teacher helped the child open the gift box). Wow ~ when children look at it, it's a square biscuit and a triangle sandwich. The teacher said that children should be invited to eat biscuits and sandwiches, but before eating, children should know about it first. At this time, the teacher let the children know that a square has four corners and four sides, and the four corners are all the same size, the four sides are all the same length, and the triangle has three corners and three sides. After a preliminary understanding of graphics, the teacher stimulated children's interest in understanding graphics. The teacher asked: children, do you know that in our life, besides biscuits, what else is square? Are there squares in the classroom? Besides rectangular gift boxes, where else have you seen rectangular ones?
-the teacher will show it after the kindergarten discussion; The wall chart, the long train, let the children observe and appreciate it. The teacher told me that the train body is rectangular and the triangle can also be used as a locomotive! The house used to be made up of squares and triangles. Let children know that the original graphics are closely related to our lives through telling.
3, in order to let children know more about graphics, hands-on operation.
-Show the wool, the teacher demonstrates, a wool is connected to make four identical corners, and then the four sides are made the same length, and a simple square comes out. The same method can guide children to make rectangles and triangles. Let children experience fun from it!
4. At the end of the course, praise the children who operate the graphic stick and encourage the children who can't operate it. Finally, share the square biscuits and triangle sandwiches in the rectangular gift box.
