This activity mainly requires children to identify plane geometric figures and classify them according to different colors and shapes. The children in the middle class are intuitive in thinking, so they should pay attention to the obvious characteristics of things in the learning process. In this math activity, children's common geometric figures are selected, so that children can operate and explore independently, exchange and learn with each other, which embodies the educational concept of playing with middle school and applying what they have learned.
Second, say the goal.
Activity goal is the starting point and destination of teaching activities and plays a guiding role. According to children's age characteristics and actual situation, establish the goals of cognition, emotion and ability, including exploring cognition and operation. The objectives are:
1, children can skillfully identify the four basic geometric figures and connect them with real life.
2. Guide children to correctly classify according to certain characteristics, regardless of size, and boldly speak their own classification process.
3. Stimulate children's interest in mathematical classification activities, organize materials as required after the activities, and develop good operating habits.
4. Emphasis and difficulty of the activity: classify the graphics according to their different characteristics (after classification, it is said that they are classified according to color and shape).
Third, talk about activity preparation.
Activity preparation serves specific activity goals, and children develop through the interaction of environment and materials. Activity preparation must adapt to the objectives, abilities, interests and needs of the activity subject, so activity preparation is:
(1) courseware making, music "Finding Friends" and "Outing", practice video.
(2) Making a number of circular, triangular, square and rectangular cards with different sizes and colors; Similar objects of four basic figures.
Fourth, talk about teaching methods and learning methods.
(1) The new syllabus of teaching methods points out that teachers should be supporters, collaborators and guides of learning activities. In the activity, we should strive to "form the cooperation and interaction between teachers and children". Therefore, in addition to preparing rich activity materials, I also tap the activity value of this activity and organize teaching in an appropriate way. I used:
1, scene creation method:
The lead-in part of the activity should not only let children find problems, but also lead to a series of questions and explorations behind, and set suspense through ways that children are interested in.
2. Demonstration method: Teachers demonstrate the graphics according to different colors and shapes through the electronic whiteboard to help them gain a certain understanding.
3. Observation: Observation can enrich children's perceptual experience and cultivate children's interest and curiosity about things around them.
4. Game method: put the educational content into interesting games, fully mobilize the enthusiasm of children to learn, and let children play while learning. In this activity, "game" runs through the activity, and the game is a main line of this teaching activity.
(2) Children who study law are the masters of learning. Taking children as the main body and creating conditions for children to participate in exploration activities not only improves children's exploration ability, but also enables children to acquire learning skills and stimulate children's interest in learning. The methods used in this activity are:
1. Operation method: refers to children's hands-on operation and inquiry learning in the process of interacting with materials. The operation of this activity is to help graphic babies sort out queues and puzzles, so that children can understand geometric figures by watching, playing and spelling.
2. Communication mode: the peers communicate with each other and discuss problems. In the process of communication, children can not only develop their language skills, but also share their experiences with their peers.
Five, said the activity process
1. Creating situations to stimulate children's interest in activities is the best teacher. Arouse children's interest in class, attract their attention, and stimulate their interest in participating in activities through rhythmic exercise. Guide the students to recall the pictures they have learned, take the opportunity to lead to the topic and explain the learning objectives.
2. Cooperate and exchange, explore new knowledge (1), sort out ideas and show the process. Teachers demonstrate the process of classification with electronic whiteboard to deepen students' understanding of graphic classification.
(2) After children try to classify and ask questions about classification, let them think about how to classify first. On the basis of independent thinking, let the children discuss in groups with the help of learning tools.
(3) Use expansion and extracurricular extension to show puzzles and inspire children to use geometric figures to puzzle freely and happily.
Guide them to think about problems, seek solutions to problems, exchange help with each other, and share the process and results of exploration. It is concluded that a new figure can be spelled with several different shapes. Children repeatedly feel and experience during the game to break through the difficulties. At the same time, it also cultivates children's initial sense of cooperation and ability.
3. Play games to find friends' music, find friends in music, and find objects similar to the cards in your hand as good friends. Deepen the understanding of classification.
4. Summing up Let the children go home and look for it, think about what is similar to a circle, triangle, rectangle and square in daily life, and tell their parents.
5. End the activity with the rhythm of the outing.
