That's right. Preschool children are 3~6 years old and are in the concrete thinking stage. Learning mathematics must start with specific things, so as to better understand the problems of mathematics. Applying mathematics to solve problems in real life can make students understand the content of mathematics from specific aspects. Mathematics in real life is visible, and it is convenient for students to understand and apply with physics teaching. Therefore, applying mathematics to solve problems in real life is the most effective way for preschool children's mathematics.
