Second grade gram and kilogram teaching plan
One of the basic concepts of reflective curriculum standard in senior two mathematics teaching is to pay attention to students' life experience and existing knowledge experience. According to this concept, I have some feelings after teaching the second volume of mathematics in grade two, and now I will do some reflection.
First, success:
1. Mathematical problems come from life and are applied to life. Although students are not familiar with kilograms and grams, teachers can arouse their feelings about them from life. First, let students feel that people's bodies are light and heavy, and then let students say that learning tools feel that objects are light and heavy. Choose things familiar to middle school students in life as teaching resources. Starting from students' existing life experience and cognitive level, let students feel that mathematics is around us, and there is mathematics everywhere in life.
2. Help students to establish the concepts of 1g and 1kg through various learning methods. Students have been exposed to quality problems in their lives and established a preliminary concept of quality, but they still lack understanding of quality units. In order to help students establish their understanding of grams and kilograms, I have adopted various learning methods in teaching to help students establish the concepts of 1 grams and kilograms.
A. Help students to establish the representations of 1g and 1kg through actual feelings. For example, through 1 binary coins and 1 bag of washing powder, let students weigh, feel the weight of 1 g and 1 kg, and feel the weight of 1000 gram ratio 1 g, and then by adding 1, kloc-0/g.
B, let students actually measure the quality of goods. In the above estimation, the results are often different from the actual quality, so tools need to be provided to help verify- Weighing? . Students all know that you need a scale to know the weight of an object. At this time, let the students talk about which scales you know, and then introduce some commonly used scales and how to use them through courseware demonstration.
C, establish the connection between knowledge by comparison. If you weigh a bag of washing powder in one hand and 1 dime in the other, how can you compare students' views on these two units? Light or heavy? Form a more vivid appearance, and it is easy to grasp the relationship between units.
Second, the shortcomings:
1. One of the new concepts of the new curriculum is to make substantial changes in students' learning methods, advocate independent, inquiry and cooperative learning methods, and promote the development of students' innovative consciousness and practical ability. In teaching, due to the failure to handle the situation of grasping time well, group cooperation is hasty and fails to achieve good practical results.
