Kindergarten Mathematics Teaching Plan: Changing Circle 1 Activity Target
1. Knowing the semicircle and ellipse, we can find these two kinds of graphs from many graphs and count their numbers.
2. You can experience the similarities and differences of circles, semicircles and ellipses from the activities and spell out the objects you are interested in.
3. Stimulate children's interest in learning graphics.
4. Develop children's observation and spatial imagination.
Activities to be prepared
1, circle, semicircle, ellipse, a number (each similar figure has different size and color, such as red circle, green circle, big circle, small circle, etc. ).
2. Goldfish, pandas, etc. It consists of several numbers.
3. Each person has one copy of operation data.
Activity process
First, recognize semicircles and ellipses and distinguish them from circles.
1, know the semicircle and compare it with the circle.
(Showing the circle) What is this? Baby circles can do magic. See what he's become? What's the difference between a semicircle and a circle?
2. Know the ellipse and compare it with the circle.
The round baby is going to change again. What has it become now?
(showing the ellipse) Who knows what this figure is called? What is the difference between an ellipse and a circle?
Second, the game: see who answered correctly.
Game: Each child holds a circle (circle, semicircle or ellipse).
For example, the teacher said round baby, and the children with round hands raised their hands and said loudly that I was round.
Third, find semicircles and ellipses in collage graphics and express their numbers electronically.
1, show the collage goldfish, let the child find out where the semicircle and ellipse are, and count the number of his circles, semicircles and ellipses, and express them by numbers.
2. Show the collage panda, let the children find out where the semicircle is and where the ellipse is, and count the number of his circles, semicircles and ellipses.
Fourth, children operate and display children's works.
Activity reflection:
In this activity,
1. First of all, in the control of time, we failed to accurately grasp the time, so the final presentation operation did not go well.
2. In terms of discipline, it is necessary to strengthen the cultivation of children's good daily behavior habits and control the discipline in the classroom in the future.
3. The important and difficult points of this activity are not outstanding. When children are looking for circles and semicircles, they should also put ellipses in the graphics, so that their knowledge can be consolidated in time.
4. When displaying the pattern composed of graphics, the demonstration was not well combined with the operation data.
This teaching and research activity can't be said to be successful, but I also learned a lot. I think I will think more, ask more questions and record more in my future study, and constantly improve my professional level, so that children can learn and grow up happily in a relaxed and happy atmosphere.
Kindergarten mathematics teaching plan: change circle 2 activity goal;
1, know semicircles and ellipses.
2. You can experience the similarities and differences of circles, semicircles and ellipses from the activities and spell out the objects you are interested in.
3. Cultivate children's interest in math activities.
Activity preparation:
1, circle, semicircle, ellipse, several (each similar figure is different in size and color, such as red circle, green circle, big circle, small circle, etc. ).
2. Flowers made by several people, such as animals, goldfish and pandas.
3. Each person has one copy of operation data.
Activity flow:
1, importing: fun circle
Teacher: Little friend, have you ever played games with the round baby? Today, the teacher brought the round baby to our Class Two. Let's welcome it together.
Teacher: round baby, it can do magic! Guess what it will become?
The child thinks and answers.
The teacher showed pictures of circle magic.
Summary: Round babies are very powerful. Give it a hand. Round baby has more powerful skills!
2. Know the semicircle.
(1) Know the semicircle and compare it with the circle.
Teacher: (pointing to the circle) What is this? The round baby is doing magic again, children. Let's see what the round baby has become.
Teacher: When you fold it in half, a circle becomes two (semicircles).
Teacher: Little friend, do you know what is semicircular?
The child thinks and answers.
The teacher showed a semicircle picture.
Summary: A circle can be turned into a semicircle when folded in half. Children, do you still want to see a round baby do magic?
3. Know the ellipse.
Teacher: Little friend, the round baby just changed the circle into a semicircle by magic. Now, the round baby is going to do magic again. What will she become this time? Please open your eyes and see what the round baby has changed.
The teacher took out the ball and pinched it.
Teacher: Who knows what this figure is called?
The student said: This is an ellipse.
Now watch it again. What's the difference between it and a circle?
4, round, oval, semicircle puzzle
Teachers and children put together puzzles on the whiteboard.
5. Children's puzzles
Children's operation, independent puzzle.
