1. Try to measure height with a height ruler, and get a preliminary understanding of the correct method of measuring height.
2. Experience a healthy lifestyle (nutrition, exercise, sleep, etc.). )
3. Cultivate children's interest in measurement and desire to explore.
4. Cultivate children's cooperative spirit.
Activity preparation:
Height ruler, pencil, a form and a blank form for recording height, video clips of children's height measurement, and recording paper.
Teaching focus:
Master the correct method of measuring things, and will carry out simple measurement activities.
Teaching difficulties:
Experience a healthy lifestyle.
Activity flow:
(1) Compare my height when I first entered kindergarten with my current height, and realize that I have grown taller.
1, you had it as soon as you entered kindergarten.
How high? Who is the shortest in our class? Who is the tallest?
2. How much taller are you now? Who grows fastest? (Make full use of the children's record sheet before class)
Summary: Every child is very young when he enters the park. Children are the tallest and the shortest. Now that everyone has grown taller, it means that we have all grown up.
(B) to understand the correct measurement methods
How tall are you now? (Display pre-measured data)
2. Will it be the same as the result measured by the teacher? (the gap between comparison and correct data)
3. Why are the measurement results different? (Watch the video to help children understand the correct measurement method)
Summary: If the measurement method is incorrect, the measurement result will be incorrect. Whether people stand up straight, whether the ruler is flat, whether they wear shoes and the height of girls' braids will all affect the measurement results. (Children measure each other and experience the correct measurement method again)
(c) Exchange discussions and experience a healthy lifestyle.
Have you grown taller? How much higher? Why do some people grow fast and others grow slowly?
2. How can we grow tall and fast? Communicating healthy lifestyles, such as balanced nutrition, strengthening exercise and ensuring sleep, can help us grow taller and faster.
Discuss a healthy lifestyle
Why are our children tall and short? How can I make myself grow taller quickly?
Summary: There are many factors that affect height, but more nutrition, more exercise and enough sleep can help us grow taller quickly.
Activity expansion:
In the corner activities, let children continue to measure the height of others in the right way, arrange posters of "Happy Growth", and invite children to promote health in middle and small classes.
Activity reflection:
The biggest feature of mathematical activities is to connect with life. Design activities that are closely related to children, so that children can bring knowledge from their own lives to the activities, so that children feel extremely cordial. "Experiencing mathematics" is advocated by modern mathematics classroom teaching. Experience refers to participating in specific mathematical activities, having a preliminary understanding of the characteristics of objects in specific situations and gaining some experience. It is a learning activity involving cognition, emotion and behavior. The importance of experience in mathematics learning. Children's wisdom is within reach, and children can operate and cooperate in the whole activity; Through various forms of games, we can consolidate new knowledge and form ability, achieve the teaching goal and achieve good teaching results.
