Fill-in-numbers game is a lesson of "Fun Mathematics" in the second volume of Grade One of Beijing Normal University Edition. Mathematicians say mathematics is interesting, but it is really difficult for children who have not yet started to learn mathematics to understand the interest contained in mathematics. In this lesson, we can appreciate the mystery from games related to mathematics and let students experience the fun. In lively situations and games, stimulate students' interest in learning, cultivate students' sense of cooperation and the spirit of active exploration; Let students master the basic methods of crossword puzzles and complete simple crossword puzzles correctly after experiencing crossword puzzles. Correctly understand the rules of the game and improve students' analytical reasoning ability; Cultivate students' observation ability, language expression ability, practical ability and the ability to solve problems by applying mathematics initially, and feel the application of mathematics in life.

If I can make full use of my children's mistakes, guide the correct answers step by step, let my children realize the truth in their own mistakes, and constantly verify and reason, my children's analytical reasoning ability will be further improved. Will my teaching goal not be realized? The beauty of such a mistake is rare. This kind of random classroom generation should be particularly exciting. It seems that teaching tact is really important for a mature teacher, and this is exactly what I lack.
