I. Activity objectives:
1, cultivate children's interest in height through activities. Develop their logical thinking ability.
2. Guide children to compare the heights of two objects and know that the comparison between height and height is relative.
Two. , activity preparation:
1. Hang balloons, a red and a green cuboid building block of the same size, two pictures of chickens and ducklings, and a velvet chair.
2. Each person sends out a material with different heights: red and green small rectangular building blocks, several cylindrical building blocks, several wooden beads, a measuring cup with different sizes, a sleeve and a plate. There are squares on the front of the plate and protruding nails on the back. Activity flow:
1. introduced the game "Who got the balloon", which aroused children's interest (attention).
Ask two children, A and B, to take pictures of the hanging balloon (no tiptoe, no jumping). You can see that A can take pictures of balloons, but B can't. (Why did Teacher A shoot the balloon and Teacher B didn't-this leads to the topic of height) 2. The child is free to explore, and the teacher guides and summarizes that the child is taller than his peers (you can also compare with the teacher), and tell who is tall and who is short or the same height. Free exchange partners can be repeated many times.
Teacher's summary: A is higher than B, and B is shorter than B; Compared with C, A is shorter than C, and 2 is taller than the vessel. Children can freely find two kinds of utensils in the activity room: for example, the thermos is higher and the cup is shorter; The combination cabinet is high and the small chair is short.
(3) The building block teacher shows a red and a green cuboid building block, and changes the placement mode for children to observe and compare: the two building blocks are flat-the height is the same; Red building blocks stand up and green building blocks lie flat-red is high and green is short; The red building blocks are laid flat and the green building blocks are erected ―― the red ones are short and the green ones are high. The teacher took down the red building block and asked, Is the green building block tall or short? (Children can't compare) This makes children understand that an object can't be compared with height, and only two or more objects can be compared with height.
3. Children can explore freely in groups again;
