Happiness is the joy and joy of people's mood. There will be a lot of happiness in one's life, and there will also be many moods and opportunities to experience happiness.

The new mathematics curriculum standard uses more "experience-process and harvest-"experience (feeling), which shows that children can't do without their own personal experience in mathematics learning. In the process of children learning mathematics, as teachers, we give them full play and let them experience it in practice, in cooperation and communication, and in contact with life, so as to truly feel the happiness brought by mathematics.
