Teaching reflection
The composition of numbers is an important part of the concept education of numbers. The whole activity embodies a harmonious relationship between teachers and children, with children as the main body and teachers as the leading factor. Most children can actively participate in learning and achieve the predetermined teaching goals. However, there are also some shortcomings in the activities. When the teacher put the picture in front, a child was blocked by the teacher, and the teacher didn't find the problem in time. If the teacher changes the questioning strategy, stands on the left to ask questions, and immediately stands on the right to ask questions to take care of all the children, then the activity will be better.
