moving target
1, which can visually detect small and large.
2. Know that small objects and large objects can be compared by comparison, and different objects have different results.
3. Further improve the ability of analysis and judgment, and have preliminary logical thinking.
4. Experience the fun of math group games.
5, preliminary training observation, comparison and reaction ability.
Activities to be prepared
1, a bunch of balloons that haven't been blown;
2. Classrooms arranged in advance.
Activity process
1, the teacher introduced the topic: children, on the way to work today, the teacher saw a very big tree, which is bigger than all the trees in our kindergarten. Have you ever seen a big tree? Arouse children's interest and further guide them to discuss "big objects they have seen"
The more the teacher talks, the deeper it gets. "So the children have seen many big things. Please look at the big objects in our classroom? " Teachers can guide children to observe the classroom with the game of "small hands turning in circles and eyes watching".
3. Teachers can follow children's footsteps and further induce children to find the contrast between big objects and small objects. For example, if a child finds that the blackboard is big, then the teacher can show a small blackboard to inspire the child that the big blackboard is bigger than the blackboard in the classroom.
After children have the concept of comparison, teachers can use games to test their mastery. At this time, a "balloon blowing" competition was held. Let the children blow a balloon at will, then compare them in groups and come up with a big one and a small one. Then the teacher put several groups of balloons together, and then let the children judge which balloon is the biggest and which balloon is the smallest. Teachers can make children think, "Why did your group have the biggest balloon just now, but now it's not?" Let children know that different objects have different sizes and different reference objects.
Teaching reflection:
Mathematics activity is a very enjoyable course for children, because there are more games and more opportunities for children to operate, but it is not so easy for children to really understand the content of this teaching activity and master it skillfully and flexibly.
