One day, when I was playing games with children, I found that children especially like to play centerfolds. Spell different shapes with inserts, but I can't describe the shapes I spell well. I taught children squares and circles in previous classes, but I didn't introduce them to the appearance and characteristics of triangles. Some children still confuse the names and characteristics of squares, circles and triangles. Therefore, in view of this situation, I designed this class: "My New Friend" to help children review and consolidate squares and circles and know triangles, so as to have a deeper understanding of graphic babies.

moving target

1. Understand the triangle and its basic characteristics.

2. Can find triangle objects in life.

3. Can simply distinguish different shapes.

4. Let children feel happy and fun, and they should learn knowledge before they know it.

5. Enhance the flexibility of thinking.

Teaching emphases and difficulties

Teaching emphasis: triangle cognition.

Teaching difficulty: I can simply distinguish different shapes.

Activities to be prepared

1. There are several graphics (squares, circles and triangles) cards, one for small triangles;

2. Draw a picture with a small triangle outline, a hand and a box of oil pastels;

Draw a square, a circle and a triangle, a tape recorder and a tape.

Activity process

1. Introduce stories to stimulate children's interest in participating in activities.

In the kingdom of mathematics, there are many graphic babies. Look who they are.

The teacher shows the graphic babies in turn: square (square) and round (circle). They made a new friend. Come and have a look. What does it look like? Let the children speak freely and express their ideas through observation.

2. The basic part requires children to operate themselves and initially perceive the basic characteristics of the triangle.

(1) Teachers and children * * * observe the big triangle together, and guide the children to say that the triangle has three sides and three angles by counting points. Teachers and children read children's songs together: "triangle, three sides, three sides walk;" Triangle, three corners, one stop at three corners. "

(2) Draw a picture. The teacher gave each child a triangle outline, let them choose their own colors to draw a triangle, and consolidate their understanding of the basic characteristics of the triangle.

3. At the end, the game: the graphic baby finds a home.

The teacher drew a circle, a square and a triangle on the ground in advance. Let the children choose their own graphics cards, line up, and put them one by one in the corresponding "home" with the music.

Four. Expand. Teachers and children use a square piece of colored paper and fold it in half to make many triangles of different sizes. Then cut the triangle and spell it out to see what figures they can spell.

Teaching reflection

After this lesson, my biggest feeling is:

1. We should fully mobilize the enthusiasm of the children in the class in class. In the course introduction, it may be that their own guidance is not comprehensive, detailed and vivid, so children generally behave calmly and their attention is easily distracted. Only a few children cooperated when answering questions. If I can design the appearance of a baby with an opening pattern in a new way, the child can keep up with my ideas.

2. There is no timely encouragement. I thought that the children's enthusiasm at the opening ceremony was not high, and I began to feel anxious again, so when the children answered my questions, I obviously showed nervousness and even forgot to encourage them. Originally, my course involved encouragement, but I forgot this link when I was nervous.

3. The clues of each link are clear, but the coherence of the course content is not strong, and there is a lack of cohesion of related words.

4. My oral English: "Then" appears many times in class, so we must pay attention to it in the future.

Generally speaking, there are many details that need to be improved. On weekdays, I should learn from my experienced colleagues the correct teaching methods and skills, and strengthen practice and consolidation in practice, so as to become an excellent kindergarten teacher.
