"Graphic Classification" of Middle School Mathematics Teaching Plan

As a teacher, we should always compile teaching plans, which will help us to accurately grasp the key points and difficulties of teaching materials, and then choose appropriate teaching methods. How to write the lesson plan? The following is my carefully arranged math teaching plan "Graphic Classification" (8 selected articles), for reference only. Welcome to reading.

The activity goal of 1 is in the middle school mathematics teaching plan "Graphic Classification"

1, have a cognitive interest in graphics.

2. Cultivate children's preliminary classification, generalization ability and observation ability.

3. Guide children to classify according to the two characteristics of graphics.

Activities to be prepared

Some triangles, rectangles and squares of different colors and sizes, homework paper, cake plates.

Focus of activities

Guide children to classify according to two characteristics of graphics.

Activity difficulty

Guide children to classify according to two characteristics of graphics.

Activity process

First, scene import

Teacher: Children, today the teacher brought a mysterious gift. You want to know what it is? (Show rectangles and triangles) What is a rectangle like?

Summary: A rectangle has four sides. Please hold out your right index finger. Let's count them together. (1, 2, 3, 4) A rectangle has four sides. It has four corners, and (1, 2, 3, 4) is a right angle.

Teacher: (showing triangles) What are triangles like?

Summary: A triangle has three sides (1, 2,3) and three angles (1, 2,3).

Teacher: (Show a square) What is a square like?

Summary: A square has four sides and four corners, all of which are right angles.

Second, guide children to observe, find the similarities and differences of graphics and classify them according to a feature.

1, Teacher: Now please compare and have a look. What's the difference between the numbers on the blackboard? (color, shape, size)

Summary: Different colors, shapes and sizes.

Teacher: There are so many numbers on the blackboard, isn't it a mess? How do we classify them? Divide the teachers first. Let's open our eyes and see what characteristics teachers are classified according to. (color)

Summary: The teacher classified all the red figures, all the yellow figures and all the green figures according to their color characteristics.

3. Do the children want to play games with the graphic baby? The teacher also prepared a copy for everyone. (Material distribution)

Teacher: Besides color classification, let's think about how to classify. Let's classify it! (Size and shape)

Summary: Some children put large rectangles, squares and triangles together, and put small rectangles, squares and triangles together, and classify them according to their size characteristics; Other children put all rectangles together, all triangles together, and all squares together, and classify them according to their shape characteristics.

Three, according to the two characteristics of graphics classification

1, the game "See who is faster".

Teacher: You are really something! The teacher wants to play an interesting game with the children. Listen to the password and get the picture. The teacher tells the characteristics of the picture baby, so that the children can find it quickly and hold it together. Are you ready? Such as: red triangle, green square, big rectangle, small triangle, yellow rectangle.

2, send surgical paper, children's surgery.

Teacher: Just now, the children operated very well. I want to give each child a piece of homework paper. Look, children, what's on this paper? What does the left side of the homework paper stand for? (Big point, small point) On the left side, the big dotted line above represents that all the placed graphics are big, and the small dotted line below represents that all the placed graphics are small; The figures in the rectangular column are all rectangles, the figures in the triangular column are all triangles, and the figures in the square column are all squares.

Question: What graphics should I put in the first row and the first column? Please start the operation now.

Teacher: Children, you have all finished your homework. That's great. Do you want to write these numbers on the surgical paper? (Yes) After school this afternoon, the teacher will give them to the children and go home as a little teacher to teach mom and dad to finish them together.

Activity expansion

Take the surgical paper tape home, stick it with mom and dad and bring it back.

Junior high school mathematics teaching plan "graphic classification" Part II Activity goal:

1 can carry out activities according to the shape characteristics of graphics and consolidate the understanding of shapes.

2 can tell their own classification reasons.

Ability to work with colleagues and try to record results.

Take an active part in math activities and experience the fun of math activities.

Activity preparation:

Experience preparation:

Children already know triangles, circles, squares, rectangles, trapezoid, ellipses and other figures.

Material preparation:

Each person has a sorting box: children's activity operation data: science, classification according to graphic characteristics, science and graphic combination.

Activity flow:

1 Show wonderful pockets and review your understanding of plane graphics.

Teacher: This is a painted pocket with many things hidden in it. Please guess what it is. The teacher read a lot in his wonderful pocket. Let me touch it first, and let some children touch out the shapes of square, angle, circle, rectangle, trapezoid and ellipse for everyone to identify and name.

2 Guide children to operate and learn to classify graphics.

Teacher: Please take out the sorting boxes and put the same shapes together.

Children operate, teachers observe and guide.

After the operation, please put all the graphics into the corresponding baskets according to their shapes, and check whether the classification is wrong.

3 After completing the calculation materials, please ask the children to observe the calculation materials "classification by graphic characteristics" and "graphic combination" to see which graphics are composed of the above patterns, count the number of each graphic, and make a record of the classification.

Teaching reflection:

"Classification by graphic features" is an activity that requires children to classify and queue according to their shape and color features. In order to attract children's attention and improve their interest in activities, according to the age characteristics of middle-class children, the scene of helping graphic babies queue up is used to stimulate children's interest, so that children can study in a relaxed and happy atmosphere and stimulate their desire to explore. In organizational form, I adopt group activities, game activities and group operations. In the activity, children's thinking is very active and they can actively express their findings in words. In this way, children's abilities can be developed in many ways. In the activity, I improve the opportunity of expression through individual answers and collective answers, and improve children's oral expression ability, reaction ability and observation ability.

2. Provide eight pieces of red beans, soybeans, black beans, peanuts and wooden beads, and several pieces of broad beans, mung beans and plastic beads for children to classify. Secondary classification marks: eight, less than eight; Three-level classification mark: it belongs to beans, not beans.

Teaching reflection:

Compared with other activities, mathematics activities in kindergartens are boring and monotonous, which easily makes children lose interest in learning. Because the children in this period are young and their logical thinking has not yet developed, I created an operable environment for the children in this activity, which is rich in materials, selective and operable. Enable children to operate materials independently. Express their ideas boldly. Children's autonomy, selectivity and independence have been fully reflected. Through a series of game activities, the preset requirements of the overall goal of the theme have been achieved. The jigsaw puzzle is more in line with children's interests and experiences, and encourages children to explore independently.
