Dare to guess and question
Before class, Teacher Zhang and the children get to know each other by guessing brain teasers. The teacher listened patiently to the children's answers to all kinds of strange ideas and told them to make bold guesses and think from unexpected angles.
? The course is about "encountering problems", and the children have not learned the corresponding knowledge. When the teacher writes down the condition that "A and B walk in opposite directions from A and B respectively" on the whiteboard, first guide the children to put forward what they don't understand. Among them, some children don't understand the meaning of the word "opposite". The teacher asked the children to express their understanding of the word, but at this time everyone's understanding is different. The teacher told the children that they could solve the problem of word meaning in mathematics by looking it up in the dictionary. After understanding the meaning of the sentences on the whiteboard, the teacher asked two students to go on stage to demonstrate the possible different positional relationships of the encounter problems, and guided the children to dare to go out of bounds and guess what might happen.
Enlighten teaching and understand thoroughly
? The teacher asked the children to draw possible positional relationships in their notebooks and then show their ideas on the blackboard. Children draw in a variety of ways. Through the teacher's step-by-step guidance, the children divide the possible situations into three categories: no meeting, meeting and meeting. Teacher Zhang then threw out one question after another and introduced the concepts of speed, time and distance. In all kinds of guesses and doubts, the children tried to sum up the relationship between different distances, and each child became the master of the classroom, successfully exploring the location relationship of the encounter problem.
The whole class is different from our classroom, with long class hours and no dependence on textbooks. In class, children open their active thinking, speak positively, are not tired, and have a lot of fun and knowledge. Teachers dare to let go, let the children talk, let the children answer themselves, and become the masters of the classroom. Such a class must be enjoyed by children.
Listening to Hongwei's Interpretation of "Panoramic" Mathematics Teaching
Have you ever seen such a math class? Teachers run supermarkets in the classroom, children get bonuses through their own efforts, get to know RMB through shopping, and solve the simple calculation of RMB through practical application. The game of "Lucky Peanut Kernel" allows children to catch peanuts and know the numbers. Children whose numbers meet certain mathematical conditions can win prizes. Establish the concept of probability by rewarding children who have carefully completed their homework to get lucky draw opportunities. When talking about the score, feel the size of the score by sharing the game of juice and cake. Teacher Zhang said that children feel the happiness of mathematics wholeheartedly through visual, tactile and other body organs. Interesting mathematics follows children's nature and allows them to learn independently through internal drive.
Repeated learning and mechanical learning have become discovery, curiosity and challenge.
Let every child become a comedian.
Use the active and playful nature to carry out real gun combat.
Ignite children's desire for love, curiosity, exploration, etc.
? Teacher Zhang talks about panoramic mathematics teaching to let children experience and learn as much as possible in solving real problems. He makes children like him, makes them feel the wonder of mathematics, and protects their interest and confidence in mathematics in the process of learning. This is the correct way to learn mathematics.
? This observation and study also inspired me deeply. Only vivid teachers can bring vivid math lessons. How to make mathematics not a burden on children's minds, but a pleasure to overcome difficulties requires us to constantly think and change the teaching methods in the classroom. It is not easy to make the course really alive, which requires me to keep learning and polishing.
