Teaching plan "Graphic Classification" Open Class of Mathematics in Middle School 1 Activity Target:
1, can carry out activities according to the shape characteristics of graphics and consolidate the understanding of shapes.
2. Be able to tell your own classification reasons.
3. Cultivate children's interest in calculation and the accuracy and agility of thinking through various sensory training.
4. Know that sorting according to different characteristics of things will have different results, and initially understand the reversibility of sorting.
Activity preparation:
Experience preparation: Young children already know triangle, circle, square, rectangle, trapezoid and ellipse.
Material preparation: one person and one sorting box. Material collocation: children's activity operation materials: science, classification according to graphic characteristics, and combination of science and graphics.
Activity flow:
1, show "wonderful pocket, review the understanding of plane graphics.
Teacher: This is a painted pocket with many things hidden in it. Please guess what it is. "Qu teacher. Teaching, Case, Network "The teacher read" There are many wonderful things in my pocket, let me touch them first ",and asked individual children to touch out shapes such as square, angle, circle, rectangle, trapezoid, ellipse, etc., so that everyone could identify and name them.
2. Guide children to operate and learn graphic classification.
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 classify and record.
Activity 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.
