Reflection on addition and subtraction courses within 7 classes in kindergarten?
This activity is a learning activity of addition and subtraction. Through previous systematic study, children have learned how to write application problems orally, how to calculate formulas and how to make simple calculations. In this activity, we focus on letting children know that the exchange of two addends does not affect the number of words, and another focus is to let them learn to listen to the number of words added up according to their learning situation. After hearing the teacher's two knocks, the children added up the two knocks and got a total. This activity is very interesting and the children like it very much. They listened carefully and calculated carefully. They can basically do the addition of numbers within 7 skillfully. Especially for those children who usually have the habit of not paying attention to lectures, such activities can exercise their concentration and the habit of paying attention to lectures.

These two key points have been well completed in this activity.

Therefore, after completing the regular learning tasks, we need to explore some new contents and some extended activities, so that children can learn new ideas in ordinary learning. Let thinking get a good exercise and learn more learning methods, which is also the significance that mathematics activities bring them to learn.

And this kind of learning needs us to learn and think, so that every learning activity is full of new ideas and feels like the first time. This is also very difficult and of course necessary.

The idea of organizing teaching in this activity is also different from that in peacetime. Instead, after the teacher demonstrates a formula, let the children think for themselves, think about which two numbers add up to 7, and then how to list the formula. It can be said that this is a backward way of thinking, and it also gives children an opportunity to broaden their horizons.
