Activity design background of excellent teaching plan 1 for small class mathematics in kindergarten.
Different shapes of triangles interest children very much. Through hands-on practice, make three sticks with the same or different lengths into triangles, so that children can further realize that there are three angles and all three sides are triangles.
moving target
1, know the triangle, know that the triangle has three sides and three angles, review the consistent number of hands and mouths, and cultivate children's observation and comparison ability.
2. Stimulate children's interest in learning graphics.
3. Be able to speak boldly in front of the group, imagine positively and improve the language expression ability.
4. Be able to listen carefully to the opinions of peers and operate independently.
Teaching emphases and difficulties
1, know triangles, and know that triangles have many shapes.
2. Distinguish between triangles and squares.
Activities to be prepared
Teaching AIDS: triangular colored paper or blow-molded paper, equilateral triangle, isosceles triangle, right triangle, acute triangle and obtuse triangle, each 1 block. Enough for each child to make 1-2 triangular sticks (different lengths) and a square colored paper.
Activity process
1. What does a triangle look like? The teacher shows an isosceles triangle and tells the children that it is a triangle. How many sides does a triangle have? How many angles?
The teacher concluded: This is a triangle. A triangle has three sides and three angles. We call any figure with three sides and three angles a triangle.
2. Review the understanding of triangles. The teacher showed a right triangle. Let children think about what shape it is. Why?
Compare it with a square and see the difference. The teacher asked the students to name a text and find out the difference between a square and a triangle.
The teacher summed up: a square has four sides, a triangle has three sides, the four sides of the square are equal in length, and the three sides of the triangle are unequal in length; A square has four corners and a triangle has three corners; The four corners of a square are the same, but the three corners of a triangle can be different. (The teacher demonstrates while talking)
4. Are they all triangles? The teacher showed all kinds of triangles. Ask the students to tell if they are triangles. Why? Children only need to answer "triangles, because they all have three sides and three angles".
Teacher's summary:
A triangle has three sides and three angles.
A triangle has many brothers. Although they look different, they are all triangular.
③ The three sides of a triangle can be different in length and the three angles can be different in size.
As long as a figure has three sides and three angles, they are triangles.
5. Let children look for something similar to a triangle in common objects.
6, children's operation. Put many sticks of different lengths on the child, and count three sticks to make a triangle (you can find sticks of the same length or sticks of different lengths; If you do it quickly, you can do the second and third.
Teaching reflection
My math class is to let children know triangles, and the difficulty is how to distinguish triangles from squares. In this teaching process, I put many sticks with different lengths on the children's desks and asked the children to count three sticks to form a triangle (you can find sticks with the same length or sticks with different lengths). By letting them operate with their hands, the children further realized that 1, a triangle has three angles and three sides. 2. The lengths of the three sides of a triangle can be different, and the sizes of the three angles can also be different.
Excellent teaching plan of small class mathematics in kindergarten "knowing triangle";
1. Guide children to initially perceive triangles, know their names and shape characteristics, and know the diversity of triangles in exploration and operation activities;
2. Triangles can be found without interference from other graphics;
3. Cultivate children's hands-on operation ability and develop the flexibility of thinking.
Activity preparation:
Teaching AIDS:
1, various triangles; Digital card;
2. Stars, diamonds and diamonds 1.
Learning tools:
1, 3 pieces of paper with different lengths (one set for each child);
2. Various graphics: circle, square, rectangle and triangle;
3. Graphic puzzles;
4, rubber pad with one hand.
Activity flow:
First, explore the operation:
1, please take three pieces of paper with different lengths and make a picture. Children's exploration activities, guided by teachers.
2, children show their own graphics, what kind of graphics teachers collectively talk about, with a few sheets of paper, there are several angles.
Second, understand the characteristics of the triangle
1, "Good boy! Now please invite today's graphic guests. " Show the triangle and guide the children to count the angles and sides of the triangle. (The teacher marks the triangle with numbers according to the angles and sides counted by the children. )
2. Show the stars, squares and diamonds to let the children know whether they are triangles.
3, show a variety of graphics, let the children put aside the triangle classification. (The second operation consolidates the understanding of triangle features)
4. Operation: Children are holding a graphic puzzle. Please find out the triangle and color in the picture.
5. Show your pictures to your parents.
Third, the activity is over.
