Children in small classes in kindergartens are generally 3-4 years old. According to the national development guide for children aged 3-6, children's knowledge of mathematics needs the following aspects:

1, interest in learning mathematics

When children perceive and discover the diversity of objects around them, they can experience and discover that mathematics can be used in many places in their lives and become interested in mathematics learning.

2. Actively explore the operation and seek answers.

Because children are interested in mathematics, they will take the initiative to explore and seek answers through different methods. In this process, their intelligence has been developed and many mathematical abilities have been improved.

3. Perceive physical objects and learn to compare.

At this stage, children can notice the obvious shape characteristics of the object, describe it in their own language, perceive the basic spatial position and orientation of the object, and understand the orientation words such as up and down, back and forth, inside and outside.

4. Understand numbers and quantities

Combining with specific things, through many comparisons, let children gradually understand the meaning of numbers and quantities.
