moving target
1, learn to compare the heights of objects intuitively and perceive the relativity of heights.
2. Learn to arrange 2-5 objects from high to low or from short to high.
3. Be able to actively participate in activities and feel the pleasure of growing taller.
Activities to be prepared
Three pictures of roosters, five pictures of puppies with different heights, and five pictures of mushroom dolls with different heights, each with a sorting column.
Activity process
First, guide children to find that height should be compared at the same level.
1, teacher: (showing pictures of three cocks with different colors) Children, today the teacher invited three cocks to play games with the children, but they were quarrelling and said they were the tallest.
Let the children help them find a way to tell who is tall and who is short, ok? (Children think) Please tell the cocks what you think and see if you can help them. (The child answers)
Young: When all three cocks stand on a line and make a comparison, you will know who is tall and who is short.
2. Sort from short to long.
Teacher: Can you arrange them from short to high? Put it on the sorting board. (Display the sorting board)
3. Compare the teacher with the child, then compare the teacher with the tall teacher, and guide the child to discover the existence of height through comparison.
Summary: I want to know who is tall and who is short, depending on who he is compared with. When he is compared with a tall man, he is short, and when he is compared with a short man, he is tall.
4. Ask the children to go on stage and operate in order: from high to short.
Show five puppies and let the children arrange them from high to low or from short to high.
Summary: According to the order from short to high, first choose the front one, then find the shortest one from the rest, and then proceed with the rest in turn. The method from high to low is as above.
Observation on the second day of junior high school: from short to high: like climbing stairs. From high to short: like going down stairs.
Third, collective operation activities: mushroom dolls are taller than their height.
Teacher: Children, we have lined up roosters and puppies. Now let's line up these mushroom dolls. Please help them line up from high to low and then from short to high.
Fourthly, through the game of "Find a friend by height", we can further understand the relativity between height and height.
Teachers' self-evaluation:
In the activity, I learned how to compare the height of objects, so that children can correctly distinguish the height of objects. In the first part, I can design to let children look for objects that can be higher than their height, so that children can be more interested and active. The second part is to learn some relatively high and low methods. I will focus on teaching children to learn direct comparison, and children should be allowed to find out for themselves. In the activity, the teacher talked too much and asked too much of the children, which did not fully reflect the role of the teacher as a guide. Teachers need to further improve their language in future activities.
Teacher evaluation:
1, there is little difference in the height of teaching AIDS, so the interference of size should be considered when preparing for the exam. 5. The operation of internal objects should be from easy to difficult.
2. The activity process should be more interesting.
When it comes to "who is taller than who, who is shorter than who", it needs to be said separately, and it is difficult for children to say.
